- This is a device driver for the 3Com Etherlink 3c501.
- Do not purchase this card, even as a joke. It's performance is horrible,
- and it breaks in many ways.

-
- Fixed (again!) the missing interrupt locking on TX/RX shifting.
- Alan Cox <Alan.Cox@linux.org>
-
- Removed calls to init_etherdev since they are no longer needed, and
- cleaned up modularization just a bit. The driver still allows only
- the default address for cards when loaded as a module, but that's
- really less braindead than anyone using a 3c501 board. :)
- 19950208 (invid@msen.com)
-
- Added traps for interrupts hitting the window as we clear and TX load
- the board. Now getting 150K/second FTP with a 3c501 card. Still playing
- with a TX-TX optimisation to see if we can touch 180-200K/second as seems
- theoretically maximum.
- 19950402 Alan Cox <Alan.Cox@linux.org>
-
- Cleaned up for 2.3.x because we broke SMP now.
- 20000208 Alan Cox <alan@redhat.com>
-
- Check up pass for 2.5. Nothing significant changed
- 20021009 Alan Cox <alan@redhat.com>

- Fixed zero fill corner case

- For the avoidance of doubt the "preferred form" of this code is one which
- is in an open non patent encumbered format. Where cryptographic key signing
- forms part of the process of creating an executable the information

- are deemed to be part of the source code.

- * DOC: 3c501 Card Notes
- *
- * Some notes on this thing if you have to hack it. [Alan]
- *
- * Some documentation is available from 3Com. Due to the boards age
- * standard responses when you ask for this will range from 'be serious'
- * to 'give it to a museum'. The documentation is incomplete and mostly
- * of historical interest anyway.
- *
- * The basic system is a single buffer which can be used to receive or
- * transmit a packet. A third command mode exists when you are setting
- * things up.
- *
- * If it's transmitting it's not receiving and vice versa. In fact the
- * time to get the board back into useful state after an operation is
- * quite large.
- *
- * The driver works by keeping the board in receive mode waiting for a
- * packet to arrive. When one arrives it is copied out of the buffer
- * and delivered to the kernel. The card is reloaded and off we go.
- *
- * When transmitting lp->txing is set and the card is reset (from
- * receive mode) [possibly losing a packet just received] to command
- * mode. A packet is loaded and transmit mode triggered. The interrupt
- * handler runs different code for transmit interrupts and can handle
- * returning to receive mode or retransmissions (yes you have to help
- * out with those too).
- *
- * DOC: Problems
- *
- * There are a wide variety of undocumented error returns from the card
- * and you basically have to kick the board and pray if they turn up. Most
- * only occur under extreme load or if you do something the board doesn't
- * like (eg touching a register at the wrong time).
- *
- * The driver is less efficient than it could be. It switches through
- * receive mode even if more transmits are queued. If this worries you buy
- * a real Ethernet card.
- *
- * The combination of slow receive restart and no real multicast
- * filter makes the board unusable with a kernel compiled for IP
- * multicasting in a real multicast environment. That's down to the board,
- * but even with no multicast programs running a multicast IP kernel is
- * in group 224.0.0.1 and you will therefore be listening to all multicasts.
- * One nv conference running over that Ethernet and you can give up.

- * Linux Ethernet device driver for the 3Com Etherlink Plus (3C505)
- * By Craig Southeren, Juha Laiho and Philip Blundell
- *
- * 3c505.c This module implements an interface to the 3Com
- * Etherlink Plus (3c505) Ethernet card. Linux device
- * driver interface reverse engineered from the Linux 3C509
- * device drivers. Some 3C505 information gleaned from
- * the Crynwr packet driver. Still this driver would not
- * be here without 3C505 technical reference provided by
- * 3Com.

-/* Theory of operation:
- *
- * The 3c505 is quite an intelligent board. All communication with it is done
- * by means of Primary Command Blocks (PCBs); these are transferred using PIO
- * through the command register. The card has 256k of on-board RAM, which is
- * used to buffer received packets. It might seem at first that more buffers
- * are better, but in fact this isn't true. From my tests, it seems that
- * more than about 10 buffers are unnecessary, and there is a noticeable
- * performance hit in having more active on the card. So the majority of the
- * card's memory isn't, in fact, used. Sadly, the card only has one transmit
- * buffer and, short of loading our own firmware into it (which is what some
- * drivers resort to) there's nothing we can do about this.
- *
- * We keep up to 4 "receive packet" commands active on the board at a time.
- * When a packet comes in, so long as there is a receive command active, the
- * board will send us a "packet received" PCB and then add the data for that
- * packet to the DMA queue. If a DMA transfer is not already in progress, we
- * set one up to start uploading the data. We have to maintain a list of
- * backlogged receive packets, because the card may decide to tell us about
- * a newly-arrived packet at any time, and we may not be able to start a DMA
- * transfer immediately (ie one may already be going on). We can't NAK the
- * PCB, because then it would throw the packet away.
- *
- * Trying to send a PCB to the card at the wrong moment seems to have bad
- * effects. If we send it a transmit PCB while a receive DMA is happening,
- * it will just NAK the PCB and so we will have wasted our time. Worse, it
- * sometimes seems to interrupt the transfer. The majority of the low-level
- * code is protected by one huge semaphore -- "busy" -- which is set whenever
- * it probably isn't safe to do anything to the card. The receive routine
- * must gain a lock on "busy" before it can start a DMA transfer, and the
- * transmit routine must gain a lock before it sends the first PCB to the card.
- * The send_pcb() routine also has an internal semaphore to protect it against
- * being re-entered (which would be disastrous) -- this is needed because
- * several things can happen asynchronously (re-priming the receiver and
- * asking the card for statistics, for example). send_pcb() will also refuse
- * to talk to the card at all if a DMA upload is happening. The higher-level
- * networking code will reschedule a later retry if some part of the driver
- * is blocked. In practice, this doesn't seem to happen very often.
- */
-
-/* This driver may now work with revision 2.x hardware, since all the read
- * operations on the HCR have been removed (we now keep our own softcopy).
- * But I don't have an old card to test it on.
- *
- * This has had the bad effect that the autoprobe routine is now a bit
- * less friendly to other devices. However, it was never very good.
- * before, so I doubt it will hurt anybody.
- */
-
-/* The driver is a mess. I took Craig's and Juha's code, and hacked it firstly
- * to make it more reliable, and secondly to add DMA mode. Many things could
- * probably be done better; the concurrency protection is particularly awful.

- That's it: only 86 bytes to set up the beast, including every extra
- command available. The 170 byte buffer at DUMP_DATA is shared between the
- Dump command (called only by the diagnostic program) and the SetMulticastList
- command.
-
- To complete the memory setup you only have to write the station address at
- SA_OFFSET and create the Tx & Rx buffer lists.
-
- The Tx command chain and buffer list is setup as follows:
- A Tx command table, with the data buffer pointing to...
- A Tx data buffer descriptor. The packet is in a single buffer, rather than
- chaining together several smaller buffers.
- A NoOp command, which initially points to itself,
- And the packet data.
-
- A transmit is done by filling in the Tx command table and data buffer,
- re-writing the NoOp command, and finally changing the offset of the last
- command to point to the current Tx command. When the Tx command is finished,
- it jumps to the NoOp, when it loops until the next Tx command changes the
- "link offset" in the NoOp. This way the 82586 never has to go through the
- slow restart sequence.
-
- The Rx buffer list is set up in the obvious ring structure. We have enough
- memory (and low enough interrupt latency) that we can avoid the complicated
- Rx buffer linked lists by alway associating a full-size Rx data buffer with
- each Rx data frame.
-
- I current use four transmit buffers starting at TX_BUF_START (0x0100), and
- use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

- net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
- This is an extension to the Linux operating system, and is covered by the
- same GNU General Public License that covers that work.
-
- Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
- This is basically Michael Hipp's ni52 driver, with a new probing
- algorithm and some minor changes to the 82586 CA and reset routines.
- Thanks a lot Michael for a really clean i82586 implementation! Unless
- otherwise documented in ni52.c, any bugs are mine.
-
- Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
- any way. The ni52 is a lot easier to modify.
-
- sources:
- ni52.c
-
- Crynwr packet driver collection was a great reference for my first
- attempt at this sucker. The 3c507 driver also helped, until I noticed
- that ni52.c was a lot nicer.
-
- EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
- Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
- stuff. Information on CardFacts is found in the Ethernet HOWTO.
- Also see <a href="http://www.3com.com/">
-
- Microprocessor Communications Support Chips, T.J. Byers, ISBN
- 0-444-01224-9, has a section on the i82586. It tells you just enough
- to know that you really don't want to learn how to program the chip.
-
- The original device probe code was stolen from ps2esdi.c
-
- Known Problems:
- Since most of the code was stolen from ni52.c, you'll run across the
- same bugs in the 0.62 version of ni52.c, plus maybe a few because of
- the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there
- shouldn't be the overrun problem that the 8K ni52 has.
-
- This driver is for a 16K adapter. It should work fine on the 64K
- adapters, but it will only use one of the 4 banks of RAM. Modifying
- this for the 64K version would require a lot of heinous bank
- switching, which I'm sure not interested in doing. If you try to
- implement a bank switching version, you'll basically have to remember
- what bank is enabled and do a switch everytime you access a memory
- location that's not current. You'll also have to remap pointers on
- the driver side, because it only knows about 16K of the memory.
- Anyone desperate or masochistic enough to try?
-
- It seems to be stable now when multiple transmit buffers are used. I
- can't see any performance difference, but then I'm working on a 386SX.
-
- Multicast doesn't work. It doesn't even pretend to work. Don't use
- it. Don't compile your kernel with multicast support. I don't know
- why.
-
- Features:
- This driver is useable as a loadable module. If you try to specify an
- IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
- search the MCA slots until it finds a 3c523 with the specified
- parameters.
-
- This driver does support multiple ethernet cards when used as a module
- (up to MAX_3C523_CARDS, the default being 4)
-
- This has been tested with both BNC and TP versions, internal and
- external transceivers. Haven't tested with the 64K version (that I
- know of).
-
- History:
- Jan 1st, 1996
- first public release
- Feb 4th, 1996
- update to 1.3.59, incorporated multicast diffs from ni52.c
- Feb 15th, 1996
- added shared irq support
- Apr 1999
- added support for multiple cards when used as a module
- added option to disable multicast as is causes problems
- Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
- Stuart Adamson <stuart.adamson@compsoc.net>
- Nov 2001
- added support for ethtool (jgarzik)

-/**
- * DOC: Traps for the unwary
- *
- * The diagram (Figure 1-1) and the POS summary disagree with the
- * "Interrupt Level" section in the manual.
- *
- * The manual contradicts itself when describing the minimum number
- * buffers in the 'configure lists' command.
- * My card accepts a buffer config of 4/4.
- *
- * Setting the SAV BP bit does not save bad packets, but
- * only enables RX on-card stats collection.
- *
- * The documentation in places seems to miss things. In actual fact
- * I've always eventually found everything is documented, it just
- * requires careful study.
- *
- * DOC: Theory Of Operation
- *
- * The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- * amount of on board intelligence that housekeeps a somewhat dumber
- * Intel NIC. For performance we want to keep the transmit queue deep
- * as the card can transmit packets while fetching others from main
- * memory by bus master DMA. Transmission and reception are driven by
- * circular buffer queues.
- *
- * The mailboxes can be used for controlling how the card traverses
- * its buffer rings, but are used only for inital setup in this
- * implementation. The exec mailbox allows a variety of commands to
- * be executed. Each command must complete before the next is
- * executed. Primarily we use the exec mailbox for controlling the
- * multicast lists. We have to do a certain amount of interesting
- * hoop jumping as the multicast list changes can occur in interrupt
- * state when the card has an exec command pending. We defer such
- * events until the command completion interrupt.
- *
- * A copy break scheme (taken from 3c59x.c) is employed whereby
- * received frames exceeding a configurable length are passed
- * directly to the higher networking layers without incuring a copy,
- * in what amounts to a time/space trade-off.
- *
- * The card also keeps a large amount of statistical information
- * on-board. In a perfect world, these could be used safely at no
- * cost. However, lacking information to the contrary, processing
- * them without races would involve so much extra complexity as to
- * make it unworthwhile to do so. In the end, a hybrid SW/HW
- * implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- * It should be possible to use two or more cards, but at this stage
- * only by loading two copies of the same module.
- *
- * The on-board 82586 NIC has trouble receiving multiple
- * back-to-back frames and so is likely to drop packets from fast
- * senders.

- help
- PPP multilink is a protocol (defined in RFC 1990) which allows you
- to combine several (logical or physical) lines into one logical PPP
- connection, so that you can utilize your full bandwidth.
+ The corresponding Linux backend driver is enabled by the
+ CONFIG_XEN_NETDEV_BACKEND option.
- This has to be supported at the other end as well and you need a
- version of the pppd daemon which understands the multilink protocol.

- Support for the Deflate compression method for PPP, which uses the
- Deflate algorithm (the same algorithm that gzip uses) to compress
- each PPP packet before it is sent over the wire. The machine at the
- other end of the PPP link (usually your ISP) has to support the
- Deflate compression method as well for this to be useful. Even if

- (usually your ISP) has to support the BSD-Compress compression
- method as well for this to be useful. Even if they don't support it,
- it is safe to say Y here.
-
- The PPP Deflate compression method ("PPP Deflate compression",
- above) is preferable to BSD-Compress, because it compresses better
- and is patent-free.
-
- Note that the BSD compression code will always be compiled as a

- repository at cvs.samba.org. Alternatively, see the
- RoaringPenguin package (<http://www.roaringpenguin.com/pppoe>)
- which contains instruction on how to use this driver (under
- the heading "Kernel mode PPPoE").

- help
- Support PPP (Point to Point Protocol) encapsulated in ATM frames.
- This implementation does not yet comply with section 8 of RFC2364,
- which can lead to bad results if the ATM peer loses state and
- changes its encapsulation unilaterally.
-
-config PPPOL2TP

- depends on EXPERIMENTAL && PPP
- help
- Support for PPP-over-L2TP socket family. L2TP is a protocol
- used by ISPs and enterprises to tunnel PPP traffic over UDP
- tunnels. L2TP is replacing PPTP for VPN uses.
-
- This kernel component handles only L2TP data packets: a
- userland daemon handles L2TP the control protocol (tunnel
- and session setup). One such daemon is OpenL2TP
- (http://openl2tp.sourceforge.net/).
-
-config SLIP
- tristate "SLIP (serial line) support"

- Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
- connect to your Internet service provider or to connect to some
- other local Unix box or if you want to configure your Linux box as a
- Slip/CSlip server for other people to dial in. SLIP (Serial Line
- Internet Protocol) is a protocol used to send Internet traffic over
- serial connections such as telephone lines or null modem cables;
- nowadays, the protocol PPP is more commonly used for this same
- purpose.
-
- Normally, your access provider has to support SLIP in order for you
- to be able to use it, but there is now a SLIP emulator called SLiRP
- around (available from
- <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
- allows you to use SLIP over a regular dial up shell connection. If
- you plan to use SLiRP, make sure to say Y to CSLIP, below. The
- NET-3-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, explains how to
- configure SLIP. Note that you don't need this option if you just
- want to run term (term is a program which gives you almost full
- Internet connectivity if you have a regular dial up shell account on
- some Internet connected Unix computer. Read
- <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
- support will enlarge your kernel by about 4 KB. If unsure, say N.

- called slip.
-
-config SLIP_COMPRESSED
- bool "CSLIP compressed headers"
- depends on SLIP
- select SLHC
- ---help---
- This protocol is faster than SLIP because it uses compression on the
- TCP/IP headers (not on the data itself), but it has to be supported
- on both ends. Ask your access provider if you are not sure and
- answer Y, just in case. You will still be able to use plain SLIP. If
- you plan to use SLiRP, the SLIP emulator (available from
- <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
- allows you to use SLIP over a regular dial up shell connection, you
- definitely want to say Y here. The NET-3-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, explains how to configure
- CSLIP. This won't enlarge your kernel.
-

- Adds additional capabilities to the SLIP driver to support the
- RELCOM line fill and keepalive monitoring. Ideal on poor quality
- analogue lines.
-
-config SLIP_MODE_SLIP6
- bool "Six bit SLIP encapsulation"
- depends on SLIP
- help
- Just occasionally you may need to run IP over hostile serial
- networks that don't pass all control characters or are only seven
- bit. Saying Y here adds an extra mode you can use with SLIP:
- "slip6". In this mode, SLIP will only send normal ASCII symbols over
- the serial device. Naturally, this has to be supported at the other
- end of the link as well. It's good enough, for example, to run IP
- over the async ports of a Camtec JNT Pad. If unsure, say N.

- Fibre Channel is a high speed serial protocol mainly used to connect
- large storage devices to the computer; it is compatible with and
- intended to replace SCSI.

-
- This is a device driver for the Allied Telesis AT1700, and
- Fujitsu FMV-181/182/181A/182A/183/184/183A/184A, which are
- straight-forward Fujitsu MB86965 implementations.
-
- Modification for Fujitsu FMV-18X cards is done by Yutaka Tamiya
- (tamy@flab.fujitsu.co.jp).
-
- Sources:
- The Fujitsu MB86965 datasheet.
-
- After the initial version of this driver was written Gerry Sawkins of
- ATI provided their EEPROM configuration code header file.
- Thanks to NIIBE Yutaka <gniibe@mri.co.jp> for bug fixes.
-
- MCA bus (AT1720) support by Rene Schmit <rene@bss.lu>
-
- Bugs:
- The MB86965 has a design flaw that makes all probes unreliable. Not
- only is it difficult to detect, it also moves around in I/O space in
- response to inb()s from other device probes!

-/* bionet.c BioNet-100 device driver for linux68k.
- *
- * Version: @(#)bionet.c 1.0 02/06/96
- *
- * Author: Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- * Some changes in bionet_poll_rx by Karl-Heinz Lohner
- *
- What is it ?
- ------------
- This driver controls the BIONET-100 LAN-Adapter which connects
- an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
- This version can be compiled as a loadable module (See the
- compile command at the bottom of this file).
- At load time, you can optionally set the debugging level and the
- fastest response time on the command line of 'insmod'.
-
- 'bionet_debug'
- controls the amount of diagnostic messages:
- 0 : no messages
- >0 : see code for meaning of printed messages
-
- 'bionet_min_poll_time' (always >=1)
- gives the time (in jiffies) between polls. Low values
- increase the system load (beware!)
-
- When loaded, a net device with the name 'bio0' becomes available,
- which can be controlled with the usual 'ifconfig' command.
-
- It is possible to compile this driver into the kernel like other
- (net) drivers. For this purpose, some source files (e.g. config-files
- makefiles, Space.c) must be changed accordingly. (You may refer to
- other drivers how to do it.) In this case, the device will be detected
- at boot time and (probably) appear as 'eth0'.
-
- This code is based on several sources:
- - The driver code for a parallel port ethernet adapter by
- Donald Becker (see file 'atp.c' from the PC linux distribution)
- - The ACSI code by Roman Hodek for the ATARI-ACSI harddisk support
- and DMA handling.
- - Very limited information about moving packets in and out of the
- BIONET-adapter from the TCP package for TOS by BioData GmbH.
-
- Theory of Operation
- -------------------
- Because the ATARI DMA port is usually shared between several
- devices (eg. harddisk, floppy) we cannot block the ACSI bus
- while waiting for interrupts. Therefore we use a polling mechanism
- to fetch packets from the adapter. For the same reason, we send
- packets without checking that the previous packet has been sent to
- the LAN. We rely on the higher levels of the networking code to detect
- missing packets and resend them.
-
- Before we access the ATARI DMA controller, we check if another
- process is using the DMA. If not, we lock the DMA, perform one or
- more packet transfers and unlock the DMA before returning.
- We do not use 'stdma_lock' unconditionally because it is unclear
- if the networking code can be set to sleep, which will happen if
- another (possibly slow) device is using the DMA controller.
-
- The polling is done via timer interrupts which periodically
- 'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
- between polls varies depending on an estimate of the net activity.
- The allowed range is given by the variable 'bionet_min_poll_time'
- for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
- for the higher (slowest) limit.
-
- Whenever a packet arrives, we switch to fastest response by setting
- the polling time to its lowest limit. If the following poll fails,
- because no packets have arrived, we increase the time for the next
- poll. When the net activity is low, the polling time effectively
- stays at its maximum value, resulting in the lowest load for the
- machine.
- */

-/* atari_pamsnet.c PAMsNet device driver for linux68k.
- *
- * Version: @(#)PAMsNet.c 0.2ß 03/31/96
- *
- * Author: Torsten Lang <Torsten.Lang@ap.physik.uni-giessen.de>
- * <Torsten.Lang@jung.de>
- *
- * This driver is based on my driver PAMSDMA.c for MiNT-Net and
- * on the driver bionet.c written by
- * Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- What is it ?
- ------------
- This driver controls the PAMsNet LAN-Adapter which connects
- an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
- This version can be compiled as a loadable module (See the
- compile command at the bottom of this file).
- At load time, you can optionally set the debugging level and the
- fastest response time on the command line of 'insmod'.
-
- 'pamsnet_debug'
- controls the amount of diagnostic messages:
- 0 : no messages
- >0 : see code for meaning of printed messages
-
- 'pamsnet_min_poll_time' (always >=1)
- gives the time (in jiffies) between polls. Low values
- increase the system load (beware!)
-
- When loaded, a net device with the name 'eth?' becomes available,
- which can be controlled with the usual 'ifconfig' command.
-
- It is possible to compile this driver into the kernel like other
- (net) drivers. For this purpose, some source files (e.g. config-files
- makefiles, Space.c) must be changed accordingly. (You may refer to
- other drivers how to do it.) In this case, the device will be detected
- at boot time and (probably) appear as 'eth0'.
-
- Theory of Operation
- -------------------
- Because the ATARI DMA port is usually shared between several
- devices (eg. harddisk, floppy) we cannot block the ACSI bus
- while waiting for interrupts. Therefore we use a polling mechanism
- to fetch packets from the adapter. For the same reason, we send
- packets without checking that the previous packet has been sent to
- the LAN. We rely on the higher levels of the networking code to detect
- missing packets and resend them.
-
- Before we access the ATARI DMA controller, we check if another
- process is using the DMA. If not, we lock the DMA, perform one or
- more packet transfers and unlock the DMA before returning.
- We do not use 'stdma_lock' unconditionally because it is unclear
- if the networking code can be set to sleep, which will happen if
- another (possibly slow) device is using the DMA controller.
-
- The polling is done via timer interrupts which periodically
- 'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
- between polls varies depending on an estimate of the net activity.
- The allowed range is given by the variable 'bionet_min_poll_time'
- for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
- for the higher (slowest) limit.
-
- Whenever a packet arrives, we switch to fastest response by setting
- the polling time to its lowest limit. If the following poll fails,
- because no packets have arrived, we increase the time for the next
- poll. When the net activity is low, the polling time effectively
- stays at its maximum value, resulting in the lowest load for the
- machine.

- * In general the DMA adaptor uses LUN 0, 5, 6 and 7 on one ID changeable
- * by the PAM's Net software.
- *
- * LUN 0 works as a harddisk. You can boot the PAM's Net driver there.
- * LUN 5 works as a harddisk and lets you access the RAM and some I/O HW
- * area. In sector 0, bytes 0x38-0x3d you find the ethernet HW address
- * of the adaptor.
- * LUN 6 works as a harddisk and lets you access the firmware ROM.
- * LUN 7 lets you send and receive packets.
- *
- * Some commands like the INQUIRY command work identical on all used LUNs.
- *
- * UNKNOWN1 seems to read some data.
- * Command length is 6 bytes.
- * UNKNOWN2 seems to read some data (command byte 1 must be !=0). The
- * following bytes seem to be something like an allocation length.
- * Command length is 6 bytes.
- * READPKT reads a packet received by the DMA adaptor.
- * Command length is 6 bytes.
- * WRITEPKT sends a packet transferred by the following DMA phase. The length
- * of the packet is transferred in command bytes 3 and 4.
- * The adaptor automatically replaces the src hw address in an ethernet
- * packet by its own hw address.
- * Command length is 6 bytes.
- * INQUIRY has the same function as the INQUIRY command supported by harddisks
- * and other SCSI devices. It lets you detect which device you found
- * at a given address.
- * Command length is 6 bytes.
- * START initializes the DMA adaptor. After this command it is able to send
- * and receive packets. There is no status byte returned!
- * Command length is 1 byte.
- * NUMPKTS gives back the number of received packets waiting in the queue in
- * the status byte.
- * Command length is 1 byte.
- * UNKNOWN3
- * UNKNOWN4 Function of these three commands is unknown.
- * UNKNOWN5 The command length of these three commands is 1 byte.
- * DESELECT immediately deselects the DMA adaptor. May important with interrupt
- * driven operation.
- * Command length is 1 byte.
- * STOP resets the DMA adaptor. After this command packets can no longer
- * be received or transferred.
- * Command length is 6 byte.

- * Fix TSO; tx performance is horrible with TSO enabled.
- * Wake on LAN.
- * Add more ethtool functions, including set ring parameters.
- * Fix abstruse irq enable/disable condition described here:
- * http://marc.theaimsgroup.com/?l=linux-netdev&m=116398508500553&w=2
- *
- * NEEDS TESTING:
- * VLAN
- * multicast
- * promiscuous mode
- * interrupt coalescing
- * SMP torture testing

- * hardware registers.
- *
- * Since the Au1000 has a coherent data cache, the receive and

+
+config CAN_VCAN
+ tristate "Virtual Local CAN Interface (vcan)"
+ ---help---
+ Similar to the network loopback devices, vcan offers a
+ virtual local CAN interface.
+
+ This driver can also be built as a module. If so, the module
+ will be called vcan.
+
+config CAN_SLCAN
+ tristate "Serial / USB serial CAN Adaptors (slcan)"
+ depends on TTY
+ ---help---
+ CAN driver for several 'low cost' CAN interfaces that are attached
+ via serial lines or via USB-to-serial adapters using the LAWICEL
+ ASCII protocol. The driver implements the tty linediscipline N_SLCAN.
+
+ As only the sending and receiving of CAN frames is implemented, this
+ driver should work with the (serial/USB) CAN hardware from:
+ www.canusb.com / www.can232.com / www.mictronics.de / www.canhack.de
+
+ Userspace tools to attach the SLCAN line discipline (slcan_attach,
+ slcand) can be found in the can-utils at the SocketCAN SVN, see
+ http://developer.berlios.de/projects/socketcan for details.
+
+ The slcan driver supports up to 10 CAN netdevices by default which
+ can be changed by the 'maxdev=xx' module option. This driver can
+ also be built as a module. If so, the module will be called slcan.
+
+config CAN_DEV
+ tristate "Platform CAN drivers with Netlink support"
+ default y
+ ---help---
+ Enables the common framework for platform CAN drivers with Netlink
+ support. This is the standard library for CAN drivers.
+ If unsure, say Y.
+
+if CAN_DEV
+
+config CAN_CALC_BITTIMING
+ bool "CAN bit-timing calculation"
+ default y
+ ---help---
+ If enabled, CAN bit-timing parameters will be calculated for the
+ bit-rate specified via Netlink argument "bitrate" when the device
+ get started. This works fine for the most common CAN controllers
+ with standard bit-rates but may fail for exotic bit-rates or CAN
+ source clock frequencies. Disabling saves some space, but then the
+ bit-timing parameters must be specified directly using the Netlink
+ arguments "tq", "prop_seg", "phase_seg1", "phase_seg2" and "sjw".
+ If unsure, say Y.
+
+config CAN_LEDS
+ bool "Enable LED triggers for Netlink based drivers"
+ depends on LEDS_CLASS
+ select LEDS_TRIGGERS
+ ---help---
+ This option adds two LED triggers for packet receive and transmit
+ events on each supported CAN device.
+
+ Say Y here if you are working on a system with led-class supported
+ LEDs and you want to use them as canbus activity indicators.
+
+config CAN_AT91
+ tristate "Atmel AT91 onchip CAN controller"
+ depends on ARCH_AT91 || COMPILE_TEST
+ ---help---
+ This is a driver for the SoC CAN controller in Atmel's AT91SAM9263
+ and AT91SAM9X5 processors.
+
+config CAN_TI_HECC
+ depends on ARM
+ tristate "TI High End CAN Controller"

+ TI devices. The device specifications are available from www.ti.com
+
+config CAN_BFIN

+
+ To compile this driver as a module, choose M here: the
+ module will be called bfin_can.
+
+config CAN_JANZ_ICAN3

+ depends on MFD_JANZ_CMODIO
+ ---help---
+ Driver for Janz VMOD-ICAN3 Intelligent CAN controller module, which
+ connects to a MODULbus carrier board.
+
+ This driver can also be built as a module. If so, the module will be
+ called janz-ican3.ko.
+
+config CAN_FLEXCAN
+ tristate "Support for Freescale FLEXCAN based chips"
+ depends on ARM || PPC
+ ---help---
+ Say Y here if you want to support for Freescale FlexCAN.
+
+config PCH_CAN
+ tristate "Intel EG20T PCH CAN controller"
+ depends on PCI && (X86_32 || COMPILE_TEST)
+ ---help---
+ This driver is for PCH CAN of Topcliff (Intel EG20T PCH) which
+ is an IOH for x86 embedded processor (Intel Atom E6xx series).
+ This driver can access CAN bus.
+
+config CAN_GRCAN
+ tristate "Aeroflex Gaisler GRCAN and GRHCAN CAN devices"
+ depends on OF
+ ---help---
+ Say Y here if you want to use Aeroflex Gaisler GRCAN or GRHCAN.
+ Note that the driver supports little endian, even though little
+ endian syntheses of the cores would need some modifications on
+ the hardware level to work.
+
+config CAN_RCAR

+ ---help---
+ Say Y here if you want to use CAN controller found on Renesas R-Car
+ SoCs.
+
+ To compile this driver as a module, choose M here: the module will

+
+/*
+ * The CC770 is a CAN controller from Bosch, which is 100% compatible
+ * with the AN82527 from Intel, but with "bugs" being fixed and some
+ * additional functionality, mainly:
+ *
+ * 1. RX and TX error counters are readable.
+ * 2. Support of silent (listen-only) mode.
+ * 3. Message object 15 can receive all types of frames, also RTR and EFF.
+ *
+ * Details are available from Bosch's "CC770_Product_Info_2007-01.pdf",
+ * which explains in detail the compatibility between the CC770 and the
+ * 82527. This driver use the additional functionality 3. on real CC770
+ * devices. Unfortunately, the CC770 does still not store the message
+ * identifier of received remote transmission request frames and
+ * therefore it's set to 0.
+ *
+ * The message objects 1..14 can be used for TX and RX while the message
+ * objects 15 is optimized for RX. It has a shadow register for reliable
+ * data receiption under heavy bus load. Therefore it makes sense to use
+ * this message object for the needed use case. The frame type (EFF/SFF)
+ * for the message object 15 can be defined via kernel module parameter
+ * "msgobj15_eff". If not equal 0, it will receive 29-bit EFF frames,
+ * otherwise 11 bit SFF messages.

+ * A CAN frame has a can_id (11 bit standard frame format OR 29 bit extended
+ * frame format) a data length code (can_dlc) which can be from 0 to 8
+ * and up to <can_dlc> data bytes as payload.
+ * Additionally a CAN frame may become a remote transmission frame if the
+ * RTR-bit is set. This causes another ECU to send a CAN frame with the
+ * given can_id.
+ *
+ * The SLCAN ASCII representation of these different frame types is:
+ * <type> <id> <dlc> <data>*
+ *
+ * Extended frames (29 bit) are defined by capital characters in the type.
+ * RTR frames are defined as 'r' types - normal frames have 't' type:
+ * t => 11 bit data frame
+ * r => 11 bit RTR frame
+ * T => 29 bit data frame
+ * R => 29 bit RTR frame
+ *
+ * The <id> is 3 (standard) or 8 (extended) bytes in ASCII Hex (base64).
+ * The <dlc> is a one byte ASCII number ('0' - '8')
+ * The <data> section has at much ASCII Hex bytes as defined by the <dlc>
+ *
+ * Examples:
+ *
+ * t1230 : can_id 0x123, can_dlc 0, no data
+ * t4563112233 : can_id 0x456, can_dlc 3, data 0x11 0x22 0x33
+ * T12ABCDEF2AA55 : extended can_id 0x12ABCDEF, can_dlc 2, data 0xAA 0x55
+ * r1230 : can_id 0x123, can_dlc 0, no data, remote transmission request

+config CAN_SOFTING

+ ---help---
+ Support for CAN cards from Softing Gmbh & some cards
+ from Vector Gmbh.
+ Softing Gmbh CAN cards come with 1 or 2 physical busses.
+ Those cards typically use Dual Port RAM to communicate
+ with the host CPU. The interface is then identical for PCI
+ and PCMCIA cards. This driver operates on a platform device,
+ which has been created by softing_cs or softing_pci driver.
+ Warning:
+ The API of the card does not allow fine control per bus, but
+ controls the 2 busses on the card together.
+ As such, some actions (start/stop/busoff recovery) on 1 bus
+ must bring down the other bus too temporarily.
+
+config CAN_SOFTING_CS
+ tristate "Softing Gmbh CAN pcmcia cards"
+ depends on PCMCIA
+ depends on CAN_SOFTING
+ ---help---
+ Support for PCMCIA cards from Softing Gmbh & some cards
+ from Vector Gmbh.
+ You need firmware for these, which you can get at
+ http://developer.berlios.de/projects/socketcan/
+ This version of the driver is written against
+ firmware version 4.6 (softing-fw-4.6-binaries.tar.gz)
+ In order to use the card as CAN device, you need the Softing generic
+ support too.

- Changelog:
-
- Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
- : Added dev_id parameter in net_interrupt(),
- : request_irq() and free_irq(). Just NULL for now.
-
- Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
- : in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
- : driver prematurely.
-
- Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
- : as an example. Disabled autoprobing in init_module(),
- : not a good thing to do to other devices while Linux
- : is running from all accounts.
-
- Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
-
- Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
- : email: ethernet@crystal.cirrus.com
-
- Alan Cox : Removed 1.2 support, added 2.1 extra counters.
-
- Andrew Morton : andrewm@uow.edu.au
- : Kernel 2.3.48
- : Handle kmalloc() failures
- : Other resource allocation fixes
- : Add SMP locks
- : Integrate Russ Nelson's ALLOW_DMA functionality back in.
- : If ALLOW_DMA is true, make DMA runtime selectable
- : Folded in changes from Cirrus (Melody Lee
- : <klee@crystal.cirrus.com>)
- : Don't call netif_wake_queue() in net_send_packet()
- : Fixed an out-of-mem bug in dma_rx()
- : Updated Documentation/networking/cs89x0.txt
-
- Andrew Morton : andrewm@uow.edu.au / Kernel 2.3.99-pre1
- : Use skb_reserve to longword align IP header (two places)
- : Remove a delay loop from dma_rx()
- : Replace '100' with HZ
- : Clean up a couple of skb API abuses
- : Added 'cs89x0_dma=N' kernel boot option
- : Correctly initialise lp->lock in non-module compile
-
- Andrew Morton : andrewm@uow.edu.au / Kernel 2.3.99-pre4-1
- : MOD_INC/DEC race fix (see
- : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html)
-
- Andrew Morton : andrewm@uow.edu.au / Kernel 2.4.0-test7-pre2
- : Enhanced EEPROM support to cover more devices,
- : abstracted IRQ mapping to support CONFIG_ARCH_CLPS7500 arch
- : (Jason Gunthorpe <jgg@ualberta.ca>)
-
- Andrew Morton : Kernel 2.4.0-test11-pre4
- : Use dev->name in request_*() (Andrey Panin)
- : Fix an error-path memleak in init_module()
- : Preserve return value from request_irq()
- : Fix type of `media' module parm (Keith Owens)
- : Use SET_MODULE_OWNER()
- : Tidied up strange request_irq() abuse in net_open().
-
- Andrew Morton : Kernel 2.4.3-pre1
- : Request correct number of pages for DMA (Hugh Dickens)
- : Select PP_ChipID _after_ unregister_netdev in cleanup_module()
- : because unregister_netdev() calls get_stats.
- : Make `version[]' __initdata
- : Uninlined the read/write reg/word functions.
-
- Oskar Schirmer : oskar@scara.com
- : HiCO.SH4 (superh) support added (irq#1, cs89x0_media=)
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2x01 (XScale ixp2x00 NPU) platform support
-
- Dmitry Pervushin : dpervushin@ru.mvista.com
- : PNX010X platform support
-
- Deepak Saxena : dsaxena@plexity.net

-
- This driver is written for the Digital Equipment Corporation series
- of DEPCA and EtherWORKS ethernet cards:
-
- DEPCA (the original)
- DE100
- DE101
- DE200 Turbo
- DE201 Turbo
- DE202 Turbo (TP BNC)
- DE210
- DE422 (EISA)
-
- The driver has been tested on DE100, DE200 and DE202 cards in a
- relatively busy network. The DE422 has been tested a little.
-
- This driver will NOT work for the DE203, DE204 and DE205 series of
- cards, since they have a new custom ASIC in place of the AMD LANCE
- chip. See the 'ewrk3.c' driver in the Linux source tree for running
- those cards.
-
- I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
- a DECstation 5000/200.

-
- =========================================================================
-
- The driver was originally based on the 'lance.c' driver from Donald
- Becker which is included with the standard driver distribution for
- linux. V0.4 is a complete re-write with only the kernel interface
- remaining from the original code.

-
-
- Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
- driver.
-
- The original DEPCA card requires that the ethernet ROM address counter
- be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
- only done when a 0x08 is read as the first address octet (to minimise
- the chances of writing over some other hardware's I/O register). The
- NICSR accesses have been changed to byte accesses for all the cards
- supported by this driver, since there is only one useful bit in the MSB
- (remote boot timeout) and it is not used. Also, there is a maximum of
- only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
- help debugging all this (and holding my feet to the fire until I got it
- right).
-
- The DE200 series boards have on-board 64kB RAM for use as a shared
- memory network buffer. Only the DE100 cards make use of a 2kB buffer
- mode which has not been implemented in this driver (only the 32kB and
- 64kB modes are supported [16kB/48kB for the original DEPCA]).
-
- At the most only 2 DEPCA cards can be supported on the ISA bus because
- there is only provision for two I/O base addresses on each card (0x300
- and 0x200). The I/O address is detected by searching for a byte sequence
- in the Ethernet station address PROM at the expected I/O address for the
- Ethernet PROM. The shared memory base address is 'autoprobed' by
- looking for the self test PROM and detecting the card name. When a
- second DEPCA is detected, information is placed in the base_addr
- variable of the next device structure (which is created if necessary),
- thus enabling ethif_probe initialization for the device. More than 2
- EISA cards can be supported, but care will be needed assigning the
- shared memory to ensure that each slot has the correct IRQ, I/O address
- and shared memory address assigned.
-
- ************************************************************************
-
- NOTE: If you are using two ISA DEPCAs, it is important that you assign
- the base memory addresses correctly. The driver autoprobes I/O 0x300
- then 0x200. The base memory address for the first device must be less
- than that of the second so that the auto probe will correctly assign the
- I/O and memory addresses on the same card. I can't think of a way to do
- this unambiguously at the moment, since there is nothing on the cards to
- tie I/O and memory information together.
-
- I am unable to test 2 cards together for now, so this code is
- unchecked. All reports, good or bad, are welcome.
-
- ************************************************************************
-
- The board IRQ setting must be at an unused IRQ which is auto-probed
- using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
- {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
- really IRQ9 in machines with 16 IRQ lines.
-
- No 16MB memory limitation should exist with this driver as DMA is not
- used and the common memory area is in low memory on the network card (my
- current system has 20MB and I've not had problems yet).
-
- The ability to load this driver as a loadable module has been added. To
- utilise this ability, you have to do <8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy depca.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) if you wish, edit the source code near line 1530 to reflect the I/O
- address and IRQ you're using (see also 5).
- 3) compile depca.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the depca configuration turned off and reboot.
- 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
- [Alan Cox: Changed the code to allow command line irq/io assignments]
- [Dave Davies: Changed the code to allow command line mem/name
- assignments]
- 6) run the net startup bits for your eth?? interface manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- Note that autoprobing is not allowed in loadable modules - the system is
- already up and running and you're messing with interrupts.
-
- To unload a module, turn off the associated interface
- 'ifconfig eth?? down' then 'rmmod depca'.
-
- To assign a base memory address for the shared memory when running as a
- loadable module, see 5 above. To include the adapter name (if you have
- no PROM but know the card name) also see 5 above. Note that this last
- option will not work with kernel built-in depca's.
-
- The shared memory assignment for a loadable module makes sense to avoid
- the 'memory autoprobe' picking the wrong shared memory (for the case of
- 2 depca's in a PC).
-
- ************************************************************************
- Support for MCA EtherWORKS cards added 11-3-98.
- Verified to work with up to 2 DE212 cards in a system (although not
- fully stress-tested).
-
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

- * Digi RightSwitch SE-X loadable device driver for Linux
- *
- * The RightSwitch is a 4 (EISA) or 6 (PCI) port etherswitch and
- * a NIC on an internal board.
- *
- * Author: Rick Richardson, rick@remotepoint.com
- * Derived from the SVR4.2 (UnixWare) driver for the same card.
- *
- * Copyright 1995-1996 Digi International Inc.
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * For information on purchasing a RightSwitch SE-4 or SE-6
- * board, please contact Digi's sales department at 1-612-912-3444
- * or 1-800-DIGIBRD. Outside the U.S., please check our Web page
- * at http://www.dgii.com for sales offices worldwide.
- *
- * OPERATION:
- * When compiled as a loadable module, this driver can operate
- * the board as either a 4/6 port switch with a 5th or 7th port
- * that is a conventional NIC interface as far as the host is
- * concerned, OR as 4/6 independent NICs. To select multi-NIC
- * mode, add "nicmode=1" on the insmod load line for the driver.
- *
- * This driver uses the "dev" common ethernet device structure
- * and a private "priv" (dev->priv) structure that contains
- * mostly DGRS-specific information and statistics. To keep
- * the code for both the switch mode and the multi-NIC mode
- * as similar as possible, I have introduced the concept of
- * "dev0"/"priv0" and "devN"/"privN" pointer pairs in subroutines
- * where needed. The first pair of pointers points to the
- * "dev" and "priv" structures of the zeroth (0th) device
- * interface associated with a board. The second pair of
- * pointers points to the current (Nth) device interface
- * for the board: the one for which we are processing data.
- *
- * In switch mode, the pairs of pointers are always the same,
- * that is, dev0 == devN and priv0 == privN. This is just
- * like previous releases of this driver which did not support
- * NIC mode.
- *
- * In multi-NIC mode, the pairs of pointers may be different.
- * We use the devN and privN pointers to reference just the
- * name, port number, and statistics for the current interface.
- * We use the dev0 and priv0 pointers to access the variables
- * that control access to the board, such as board address
- * and simulated 82596 variables. This is because there is
- * only one "fake" 82596 that serves as the interface to
- * the board. We do not want to try to keep the variables
- * associated with this 82596 in sync across all devices.
- *
- * This scheme works well. As you will see, except for
- * initialization, there is very little difference between
- * the two modes as far as this driver is concerned. On the
- * receive side in NIC mode, the interrupt *always* comes in on
- * the 0th interface (dev0/priv0). We then figure out which
- * real 82596 port it came in on from looking at the "chan"
- * member that the board firmware adds at the end of each
- * RBD (a.k.a. TBD). We get the channel number like this:
- * int chan = ((I596_RBD *) S2H(cbp->xmit.tbdp))->chan;
- *
- * On the transmit side in multi-NIC mode, we specify the
- * output 82596 port by setting the new "dstchan" structure
- * member that is at the end of the RFD, like this:
- * priv0->rfdp->dstchan = privN->chan;
- *
- * TODO:
- * - Multi-NIC mode is not yet supported when the driver is linked
- * into the kernel.
- * - Better handling of multicast addresses.
- *
- * Fixes:
- * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
- * - fix dgrs_found_device wrt checking kmalloc return and
- * rollbacking the partial steps of the whole process when
- * one of the devices can't be allocated. Fix SET_MODULE_OWNER
- * on the loop to use devN instead of repeated calls to dev.
- *
- * davej <davej@suse.de> - 9/2/2001
- * - Enable PCI device before reading ioaddr/irq
- *

-
- The E2100 series ethercard is a fairly generic shared memory 8390
- implementation. The only unusual aspect is the way the shared memory
- registers are set: first you do an inb() in what is normally the
- station address region, and the low three bits of next outb() *address*
- is used as the write value for that register. Either someone wasn't
- too used to dem bit en bites, or they were trying to obfuscate the
- programming interface.
-
- There is an additional complication when setting the window on the packet
- buffer. You must first do a read into the packet buffer region with the
- low 8 address bits the address setting the page for the start of the packet
- buffer window, and then do the above operation. See mem_on() for details.
-
- One bug on the chip is that even a hard reset won't disable the memory
- window, usually resulting in a hung machine if mem_off() isn't called.
- If this happens, you must power down the machine for about 30 seconds.

-
- Things remaining to do:
- Better record keeping of errors.
- Eliminate transmit interrupt to reduce overhead.
- Implement "concurrent processing". I won't be doing it!
-
- Bugs:
-
- If you have a problem of not detecting the 82595 during a
- reboot (warm reset), disable the FLASH memory should fix it.
- This is a compatibility hardware problem.
-
- Versions:
- 0.13b basic ethtool support (aris, 09/13/2004)
- 0.13a in memory shortage, drop packets also in board
- (Michael Westermann <mw@microdata-pos.de>, 07/30/2002)
- 0.13 irq sharing, rewrote probe function, fixed a nasty bug in
- hardware_send_packet and a major cleanup (aris, 11/08/2001)
- 0.12d fixing a problem with single card detected as eight eth devices
- fixing a problem with sudden drop in card performance
- (chris (asdn@go2.pl), 10/29/2001)
- 0.12c fixing some problems with old cards (aris, 01/08/2001)
- 0.12b misc fixes (aris, 06/26/2000)
- 0.12a port of version 0.12a of 2.2.x kernels to 2.3.x
- (aris (aris@conectiva.com.br), 05/19/2000)
- 0.11e some tweaks about multiple cards support (PdP, jul/aug 1999)
- 0.11d added __initdata, __init stuff; call spin_lock_init
- in eepro_probe1. Replaced "eepro" by dev->name. Augmented
- the code protected by spin_lock in interrupt routine
- (PdP, 12/12/1998)
- 0.11c minor cleanup (PdP, RMC, 09/12/1998)
- 0.11b Pascal Dupuis (dupuis@lei.ucl.ac.be): works as a module
- under 2.1.xx. Debug messages are flagged as KERN_DEBUG to
- avoid console flooding. Added locking at critical parts. Now
- the dawn thing is SMP safe.
- 0.11a Attempt to get 2.1.xx support up (RMC)
- 0.11 Brian Candler added support for multiple cards. Tested as
- a module, no idea if it works when compiled into kernel.
-
- 0.10e Rick Bressler notified me that ifconfig up;ifconfig down fails
- because the irq is lost somewhere. Fixed that by moving
- request_irq and free_irq to eepro_open and eepro_close respectively.
- 0.10d Ugh! Now Wakeup works. Was seriously broken in my first attempt.
- I'll need to find a way to specify an ioport other than
- the default one in the PnP case. PnP definitively sucks.
- And, yes, this is not the only reason.
- 0.10c PnP Wakeup Test for 595FX. uncomment #define PnPWakeup;
- to use.
- 0.10b Should work now with (some) Pro/10+. At least for
- me (and my two cards) it does. _No_ guarantee for
- function with non-Pro/10+ cards! (don't have any)
- (RMC, 9/11/96)
-
- 0.10 Added support for the Etherexpress Pro/10+. The
- IRQ map was changed significantly from the old
- pro/10. The new interrupt map was provided by
- Rainer M. Canavan (Canavan@Zeus.cs.bonn.edu).
- (BCH, 9/3/96)
-
- 0.09 Fixed a race condition in the transmit algorithm,
- which causes crashes under heavy load with fast
- pentium computers. The performance should also
- improve a bit. The size of RX buffer, and hence
- TX buffer, can also be changed via lilo or insmod.
- (BCH, 7/31/96)
-
- 0.08 Implement 32-bit I/O for the 82595TX and 82595FX
- based lan cards. Disable full-duplex mode if TPE
- is not used. (BCH, 4/8/96)
-
- 0.07a Fix a stat report which counts every packet as a
- heart-beat failure. (BCH, 6/3/95)
-
- 0.07 Modified to support all other 82595-based lan cards.
- The IRQ vector of the EtherExpress Pro will be set
- according to the value saved in the EEPROM. For other
- cards, I will do autoirq_request() to grab the next
- available interrupt vector. (BCH, 3/17/95)
-
- 0.06a,b Interim released. Minor changes in the comments and
- print out format. (BCH, 3/9/95 and 3/14/95)
-
- 0.06 First stable release that I am comfortable with. (BCH,
- 3/2/95)
-
- 0.05 Complete testing of multicast. (BCH, 2/23/95)
-
- 0.04 Adding multicast support. (BCH, 2/14/95)
-
- 0.03 First widely alpha release for public testing.
- (BCH, 2/14/95)

- This driver is written by cutting and pasting the skeleton.c driver

- Details of the i82595.
-
-You will need either the datasheet or the user manual to understand what
-is going on here. The 82595 is very different from the 82586, 82593.
-
-The receive algorithm in eepro_rx() is just an implementation of the
-RCV ring structure that the Intel 82595 imposes at the hardware level.
-The receive buffer is set at 24K, and the transmit buffer is 8K. I
-am assuming that the total buffer memory is 32K, which is true for the
-Intel EtherExpress Pro/10. If it is less than that on a generic card,
-the driver will be broken.
-
-The transmit algorithm in the hardware_send_packet() is similar to the
-one in the eepro_rx(). The transmit buffer is a ring linked list.
-I just queue the next available packet to the end of the list. In my
-system, the 82595 is so fast that the list seems to always contain a
-single packet. In other systems with faster computers and more congested
-network traffics, the ring linked list should improve performance by
-allowing up to 8K worth of packets to be queued.
-
-The sizes of the receive and transmit buffers can now be changed via lilo
-or insmod. Lilo uses the appended line "ether=io,irq,debug,rx-buffer,eth0"
-where rx-buffer is in KB unit. Modules uses the parameter mem which is
-also in KB unit, for example "insmod io=io-address irq=0 mem=rx-buffer."
-The receive buffer has to be more than 3K or less than 29K. Otherwise,
-it is reset to the default of 24K, and, hence, 8K for the trasnmit
-buffer (transmit-buffer = 32K - receive-buffer).

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
-single-chip fast Ethernet controller for PCI, as used on the Intel
-EtherExpress Pro 100 adapter.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line. While it's
-possible to share PCI interrupt lines, it negatively impacts performance and
-only recent kernels support it.
-
-III. Driver operation
-
-IIIA. General
-The Speedo3 is very similar to other Intel network chips, that is to say
-"apparently designed on a different planet". This chips retains the complex
-Rx and Tx descriptors and multiple buffers pointers as previous chips, but
-also has simplified Tx and Rx buffer modes. This driver uses the "flexible"
-Tx mode, but in a simplified lower-overhead manner: it associates only a
-single buffer descriptor with each frame descriptor.
-
-Despite the extra space overhead in each receive skbuff, the driver must use
-the simplified Rx buffer mode to assure that only a single data buffer is
-associated with each RxFD. The driver implements this by reserving space
-for the Rx descriptor at the head of each Rx skbuff.
-
-The Speedo-3 has receive and command unit base addresses that are added to
-almost all descriptor pointers. The driver sets these to zero, so that all
-pointer fields are absolute addresses.
-
-The System Control Block (SCB) of some previous Intel chips exists on the
-chip in both PCI I/O and memory space. This driver uses the I/O space
-registers, but might switch to memory mapped mode to better support non-x86
-processors.
-
-IIIB. Transmit structure
-
-The driver must use the complex Tx command+descriptor mode in order to
-have a indirect pointer to the skbuff data section. Each Tx command block
-(TxCB) is associated with two immediately appended Tx Buffer Descriptor
-(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the
-speedo_private data structure for each adapter instance.
-
-The newer i82558 explicitly supports this structure, and can read the two
-TxBDs in the same PCI burst as the TxCB.
-
-This ring structure is used for all normal transmit packets, but the
-transmit packet descriptors aren't long enough for most non-Tx commands such
-as CmdConfigure. This is complicated by the possibility that the chip has
-already loaded the link address in the previous descriptor. So for these
-commands we convert the next free descriptor on the ring to a NoOp, and point
-that descriptor's link to the complex command.
-
-An additional complexity of these non-transmit commands are that they may be
-added asynchronous to the normal transmit queue, so we disable interrupts
-whenever the Tx descriptor ring is manipulated.
-
-A notable aspect of these special configure commands is that they do
-work with the normal Tx ring entry scavenge method. The Tx ring scavenge
-is done at interrupt time using the 'dirty_tx' index, and checking for the
-command-complete bit. While the setup frames may have the NoOp command on the
-Tx ring marked as complete, but not have completed the setup command, this
-is not a problem. The tx_ring entry can be still safely reused, as the
-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.
-
-Commands may have bits set e.g. CmdSuspend in the command word to either
-suspend or stop the transmit/command unit. This driver always flags the last
-command with CmdSuspend, erases the CmdSuspend in the previous command, and
-then issues a CU_RESUME.
-Note: Watch out for the potential race condition here: imagine
- erasing the previous suspend
- the chip processes the previous command
- the chip processes the final command, and suspends
- doing the CU_RESUME
- the chip processes the next-yet-valid post-final-command.
-So blindly sending a CU_RESUME is only safe if we do it immediately after
-after erasing the previous CmdSuspend, without the possibility of an
-intervening delay. Thus the resume command is always within the
-interrupts-disabled region. This is a timing dependence, but handling this
-condition in a timing-independent way would considerably complicate the code.
-
-Note: In previous generation Intel chips, restarting the command unit was a
-notoriously slow process. This is presumably no longer true.
-
-IIIC. Receive structure
-
-Because of the bus-master support on the Speedo3 this driver uses the new
-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
-This scheme allocates full-sized skbuffs as receive buffers. The value
-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
-trade-off the memory wasted by passing the full-sized skbuff to the queue
-layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-For small frames the copying cost is negligible (esp. considering that we
-are pre-loading the cache with immediately useful header information), so we
-allocate a new, minimally-sized skbuff. For large frames the copying cost
-is non-trivial, and the larger copy might flush the cache of useful data, so
-we pass up the skbuff the packet was received into.
-
-IV. Notes
-
-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
-that stated that I could disclose the information. But I still resent
-having to sign an Intel NDA when I'm helping Intel sell their own product!

-/* Intel EtherExpress 16 device driver for Linux
- *
- * Written by John Sullivan, 1995
- * based on original code by Donald Becker, with changes by
- * Alan Cox and Pauline Middelink.
- *
- * Support for 8-bit mode by Zoltan Szilagyi <zoltans@cs.arizona.edu>
- *
- * Many modifications, and currently maintained, by
- * Philip Blundell <philb@gnu.org>
- * Added the Compaq LTE Alan Cox <alan@redhat.com>
- * Added MCA support Adam Fritzler <mid@auk.cx>
- *
- * Note - this driver is experimental still - it has problems on faster
- * machines. Someone needs to sit down and go through it line by line with
- * a databook...
- */
-
-/* The EtherExpress 16 is a fairly simple card, based on a shared-memory
- * design using the i82586 Ethernet coprocessor. It bears no relationship,
- * as far as I know, to the similarly-named "EtherExpress Pro" range.
- *
- * Historically, Linux support for these cards has been very bad. However,
- * things seem to be getting better slowly.
- */
-
-/* If your card is confused about what sort of interface it has (eg it
- * persistently reports "10baseT" when none is fitted), running 'SOFTSET /BART'
- * or 'SOFTSET /LISA' from DOS seems to help.
- */
-
-/* Here's the scoop on memory mapping.
- *
- * There are three ways to access EtherExpress card memory: either using the
- * shared-memory mapping, or using PIO through the dataport, or using PIO
- * through the "shadow memory" ports.
- *
- * The shadow memory system works by having the card map some of its memory
- * as follows:
- *
- * (the low five bits of the SMPTR are ignored)
- *
- * base+0x4000..400f memory at SMPTR+0..15
- * base+0x8000..800f memory at SMPTR+16..31
- * base+0xc000..c007 dubious stuff (memory at SMPTR+16..23 apparently)
- * base+0xc008..c00f memory at 0x0008..0x000f
- *
- * This last set (the one at c008) is particularly handy because the SCB
- * lives at 0x0008. So that set of ports gives us easy random access to data
- * in the SCB without having to mess around setting up pointers and the like.
- * We always use this method to access the SCB (via the scb_xx() functions).
- *
- * Dataport access works by aiming the appropriate (read or write) pointer
- * at the first address you're interested in, and then reading or writing from
- * the dataport. The pointers auto-increment after each transfer. We use
- * this for data transfer.
- *
- * We don't use the shared-memory system because it allegedly doesn't work on
- * all cards, and because it's a bit more prone to go wrong (it's one more
- * thing to configure...).
- */
-
-/* Known bugs:
- *
- * - The card seems to want to give us two interrupts every time something
- * happens, where just one would be better.
- */
-
-/*
- *
- * Note by Zoltan Szilagyi 10-12-96:
- *
- * I've succeeded in eliminating the "CU wedged" messages, and hence the
- * lockups, which were only occurring with cards running in 8-bit mode ("force
- * 8-bit operation" in Intel's SoftSet utility). This version of the driver
- * sets the 82586 and the ASIC to 8-bit mode at startup; it also stops the
- * CU before submitting a packet for transmission, and then restarts it as soon
- * as the process of handing the packet is complete. This is definitely an
- * unnecessary slowdown if the card is running in 16-bit mode; therefore one
- * should detect 16-bit vs 8-bit mode from the EEPROM settings and act
- * accordingly. In 8-bit mode with this bugfix I'm getting about 150 K/s for
- * ftp's, which is significantly better than I get in DOS, so the overhead of
- * stopping and restarting the CU with each transmit is not prohibitive in
- * practice.
- *
- * Update by David Woodhouse 11/5/99:
- *
- * I've seen "CU wedged" messages in 16-bit mode, on the Alpha architecture.
- * I assume that this is because 16-bit accesses are actually handled as two
- * 8-bit accesses.

- Linux driver for Racal-Interlan ES3210 EISA Network Adapter

- Copyright (C) 1996, Paul Gortmaker.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- Information and Code Sources:
-
- 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
-
- 2) Once again Russ Nelson's asm packet driver provided additional info.
-
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
- Too bad it doesn't work -- see below.
-
- The ES3210 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- Which rules out using eth_io_copy_and_sum() in this driver.
-
- Apparently there are two slightly different revisions of the
- card, since there are two distinct EISA cfg files (!rii0101.cfg
- and !rii0102.cfg) One has media select in the cfg file and the
- other doesn't. Hopefully this will work with either.
-
- That is about all I can tell you about it, having never actually
- even seen one of these cards. :) Try http://www.interlan.com
- if you want more info.
-
- Thanks go to Mark Salazar for testing v0.02 of this driver.
-
- Bugs, to-fix, etc:
-
- 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
- mem values just read 0xff all the time. Hrrmpf. Apparently the
- same happens with the packet driver as the code for reading
- these registers is disabled there. In the meantime, boot with:
- ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
- shared memory detection. (The i/o port detection is okay.)
-
- 2) Module support currently untested. Probably works though.

-
- Written 1994-1999 by Mika Kuoppala
-
- Copyright (C) 1994-1999 by Mika Kuoppala
- Based on skeleton.c and heavily on at1700.c by Donald Becker
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as miku@iki.fi
-
- This driver supports following cards :
- - ICL EtherTeam 16i
- - ICL EtherTeam 32 EISA
- (Uses true 32 bit transfers rather than 16i compability mode)
-
- Example Module usage:
- insmod eth16i.o io=0x2a0 mediatype=bnc
-
- mediatype can be one of the following: bnc,tp,dix,auto,eprom
-
- 'auto' will try to autoprobe mediatype.
- 'eprom' will use whatever type defined in eprom.
-
- I have benchmarked driver with PII/300Mhz as a ftp client
- and 486/33Mhz as a ftp server. Top speed was 1128.37 kilobytes/sec.

- Revision history:
-
- Version Date Description
-
- 0.01 15.12-94 Initial version (card detection)
- 0.02 23.01-95 Interrupt is now hooked correctly
- 0.03 01.02-95 Rewrote initialization part
- 0.04 07.02-95 Base skeleton done...
- Made a few changes to signature checking
- to make it a bit reliable.
- - fixed bug in tx_buf mapping
- - fixed bug in initialization (DLC_EN
- wasn't enabled when initialization
- was done.)
- 0.05 08.02-95 If there were more than one packet to send,
- transmit was jammed due to invalid
- register write...now fixed
- 0.06 19.02-95 Rewrote interrupt handling
- 0.07 13.04-95 Wrote EEPROM read routines
- Card configuration now set according to
- data read from EEPROM
- 0.08 23.06-95 Wrote part that tries to probe used interface
- port if AUTO is selected
-
- 0.09 01.09-95 Added module support
-
- 0.10 04.09-95 Fixed receive packet allocation to work
- with kernels > 1.3.x
-
- 0.20 20.09-95 Added support for EtherTeam32 EISA
-
- 0.21 17.10-95 Removed the unnecessary extern
- init_etherdev() declaration. Some
- other cleanups.
-
- 0.22 22.02-96 Receive buffer was not flushed
- correctly when faulty packet was
- received. Now fixed.
-
- 0.23 26.02-96 Made resetting the adapter
- more reliable.
-
- 0.24 27.02-96 Rewrote faulty packet handling in eth16i_rx
-
- 0.25 22.05-96 kfree() was missing from cleanup_module.
-
- 0.26 11.06-96 Sometimes card was not found by
- check_signature(). Now made more reliable.
-
- 0.27 23.06-96 Oops. 16 consecutive collisions halted
- adapter. Now will try to retransmit
- MAX_COL_16 times before finally giving up.
-
- 0.28 28.10-97 Added dev_id parameter (NULL) for free_irq
-
- 0.29 29.10-97 Multiple card support for module users
-
- 0.30 30.10-97 Fixed irq allocation bug.
- (request_irq moved from probe to open)
-
- 0.30a 21.08-98 Card detection made more relaxed. Driver
- had problems with some TCP/IP-PROM boots
- to find the card. Suggested by
- Kurt Huwig <kurt@huwig.de>
-
- 0.31 28.08-98 Media interface port can now be selected
- with module parameters or kernel
- boot parameters.
-
- 0.32 31.08-98 IRQ was never freed if open/close
- pair wasn't called. Now fixed.
-
- 0.33 10.09-98 When eth16i_open() was called after
- eth16i_close() chip never recovered.
- Now more shallow reset is made on
- close.
-
- 0.34 29.06-99 Fixed one bad #ifdef.
- Changed ioaddr -> io for consistency
-
- 0.35 01.07-99 transmit,-receive bytes were never
- updated in stats.
-
- Bugs:
- In some cases the media interface autoprobing code doesn't find
- the correct interface type. In this case you can
- manually choose the interface type in DOS with E16IC.EXE which is
- configuration software for EtherTeam16i and EtherTeam32 cards.
- This is also true for IRQ setting. You cannot use module
- parameter to configure IRQ of the card (yet).
-
- To do:
- - Real multicast support
- - Rewrite the media interface autoprobing code. Its _horrible_ !
- - Possibly merge all the MB86965 specific code to external
- module for use by eth16.c and Donald's at1700.c
- - IRQ configuration with module parameter. I will do
- this when i will get enough info about setting
- irq without configuration utility.

+ * Additional explanation of problems with locking by Alan Cox:
+ *
+ * "The author (me) didn't use spin_lock_irqsave because the slowness of the
+ * card means that approach caused horrible problems like losing serial data
+ * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA
+ * chips with FPGA front ends.
+ *
+ * Ok the logic behind the 8390 is very simple:
+ *
+ * Things to know
+ * - IRQ delivery is asynchronous to the PCI bus
+ * - Blocking the local CPU IRQ via spin locks was too slow
+ * - The chip has register windows needing locking work
+ *
+ * So the path was once (I say once as people appear to have changed it
+ * in the mean time and it now looks rather bogus if the changes to use
+ * disable_irq_nosync_irqsave are disabling the local IRQ)
+ *
+ *
+ * Take the page lock
+ * Mask the IRQ on chip
+ * Disable the IRQ (but not mask locally- someone seems to have
+ * broken this with the lock validator stuff)
+ * [This must be _nosync as the page lock may otherwise
+ * deadlock us]
+ * Drop the page lock and turn IRQs back on
+ *
+ * At this point an existing IRQ may still be running but we can't
+ * get a new one
+ *
+ * Take the lock (so we know the IRQ has terminated) but don't mask
+ * the IRQs on the processor
+ * Set irqlock [for debug]
+ *
+ * Transmit (slow as ****)
+ *
+ * re-enable the IRQ
+ *
+ *
+ * We have to use disable_irq because otherwise you will get delayed
+ * interrupts on the APIC bus deadlocking the transmit path.
+ *
+ * Quite hairy but the chip simply wasn't designed for SMP and you can't
+ * even ACK an interrupt without risking corrupting other parallel
+ * activities on the chip." [lkml, 25 Jul 2007]
