INTRODUCTION. - - This is a set of Ethernet drivers for the D-Link DE-600/DE-620 - pocket adapters, for the parallel port on a Linux based machine. - Some adapter "clones" will also work. Xircom is _not_ a clone... - These drivers _can_ be used as loadable modules, - and were developed for use on Linux 1.1.13 and above. - For use on Linux 1.0.X, or earlier releases, see below. - - I have used these drivers for NFS, ftp, telnet and X-clients on - remote machines. Transmissions with ftp seems to work as - good as can be expected (i.e. > 80k bytes/sec) from a - parallel port...:-) Receive speeds will be about 60-80% of this. - Depending on your machine, somewhat higher speeds can be achieved. - - All comments/fixes to Bjorn Ekwall (bj0rn@blox.se). - - - 2.

FILES IN THIS RELEASE. - - README.DLINK This file. - de600.c The Source (may it be with You :-) for the DE-600 - de620.c ditto for the DE-620 - de620.h Macros for de620.c - - If you are upgrading from the d-link tar release, there will - also be a "dlink-patches" file that will patch Linux 1.1.18: - linux/drivers/net/Makefile - linux/drivers/net/CONFIG - linux/drivers/net/MODULES - linux/drivers/net/Space.c - linux/config.in - Apply the patch by: - "cd /usr/src; patch -p0 < linux/drivers/net/dlink-patches" - The old source, "linux/drivers/net/d_link.c", can be removed. - - - 4. INSTALLATION. - - o Get the latest net binaries, according to current net.wisdom. - - o Read the NET-2 and Ethernet HOWTOs and modify your setup. - - o If your parallel port has a strange address or irq, - modify "linux/drivers/net/CONFIG" accordingly, or adjust - the parameters in the "tuning" section in the sources. - - If you are going to use the drivers as loadable modules, do _not_ - enable them while doing "make config", but instead make sure that - the drivers are included in "linux/drivers/net/MODULES". - - If you are _not_ going to use the driver(s) as loadable modules, - but instead have them included in the kernel, remember to enable - the drivers while doing "make config". - - o To include networking and DE600/DE620 support in your kernel: - # cd /linux - (as modules:) - # make config (answer yes on CONFIG_NET and CONFIG_INET) - (else included in the kernel:) - # make config (answer yes on CONFIG _NET, _INET and _DE600 or _DE620) - # make clean - # make zImage (or whatever magic you usually do) - - o I use lilo to boot multiple kernels, so that I at least - can have one working kernel :-). If you do too, append - these lines to /etc/lilo/config: - - image = /linux/zImage - label = newlinux - root = /dev/hda2 (or whatever YOU have...) - - # /etc/lilo/install - - o Do "sync" and reboot the new kernel with a D-Link - DE-600/DE-620 pocket adapter connected. - - o The adapter can be configured with ifconfig eth? - where the actual number is decided by the kernel - when the drivers are initialized. - - - 5. "PROBLEMS" AND TUNING, - - o If you see error messages from the driver, and if the traffic - stops on the adapter, try to do "ifconfig" and "route" once - more, just as in "rc.inet1". This should take care of most - problems, including effects from power loss, or adapters that - aren't connected to the printer port in some way or another. - You can somewhat change the behaviour by enabling/disabling - the macro SHUTDOWN_WHEN_LOST in the "tuning" section. - For the DE-600 there is another macro, CHECK_LOST_DE600, - that you might want to read about in the "tuning" section. - - o Some machines have trouble handling the parallel port and - the adapter at high speed. If you experience problems: - - DE-600: - - The adapter is not recognized at boot, i.e. an Ethernet - address of 00:80:c8:... is not shown, try to add another - "; SLOW_DOWN_IO" - at DE600_SLOW_DOWN in the "tuning" section. As a last resort, - uncomment: "#define REALLY_SLOW_IO" (see <asm/io.h> for hints). - - - You experience "timeout" messages: first try to add another - "; SLOW_DOWN_IO" - at DE600_SLOW_DOWN in the "tuning" section, _then_ try to - increase the value (original value: 5) at - "if (tickssofar < 5)" near line 422. - - DE-620: - - Your parallel port might be "sluggish". To cater for - this, there are the macros LOWSPEED and READ_DELAY/WRITE_DELAY - in the "tuning" section. Your first step should be to enable - LOWSPEED, and after that you can "tune" the XXX_DELAY values. - - o If the adapter _is_ recognized at boot but you get messages - about "Network Unreachable", then the problem is probably - _not_ with the driver. Check your net configuration instead - (ifconfig and route) in "rc.inet1". - - o There is some rudimentary support for debugging, look at - the source. Use "-DDE600_DEBUG=3" or "-DDE620_DEBUG=3" - when compiling, or include it in "linux/drivers/net/CONFIG". - IF YOU HAVE PROBLEMS YOU CAN'T SOLVE: PLEASE COMPILE THE DRIVER - WITH DEBUGGING ENABLED, AND SEND ME THE RESULTING OUTPUT! - - - 6. USING THE DRIVERS WITH EARLIER RELEASES. - - The later 1.1.X releases of the Linux kernel include some - changes in the networking layer (a.k.a. NET3). This affects - these drivers in a few places. The hints that follow are - _not_ tested by me, since I don't have the disk space to keep - all releases on-line. - Known needed changes to date: - - release patchfile: some patches will fail, but they should - be easy to apply "by hand", since they are trivial. - (Space.c: d_link_init() is now called de600_probe()) - - de600.c: change "mark_bh(NET_BH)" to "mark_bh(INET_BH)". - - de620.c: (maybe) change the code around "netif_rx(skb);" to be - similar to the code around "dev_rint(...)" in de600.c - - - 7.
