The attached fixes an oops in the usbnet driver. The same patch is
in 2.6.21-rc1, but that one has many whitespace changes. This is much

I just got a "ZyXEL Prestige USB Adapter" that is actually RTL8150
adapter. Here is the relevant /proc/bus/usb/devices output (after
adding the vendor/product IDs to the driver):
T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#=119 Spd=12 MxCh= 0

S: Manufacturer=ZyXEL
S: Product=Prestige USB Adapter
S: SerialNumber=1027
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=120mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=ff Driver=rtl8150

E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=1ms
This patch adds the ZyXEL vendor ID to the rtl8150.c driver. The
device has absolutely no identifying marks on the outside for model
type, just a serial number, and I can't find anything on ZyXEL's
website, so I called the product ID PRODUCT_ID_PRESTIGE to match the
product string.

Noticed that my zd1201 adapter isn't "seen" by hal and NetworkManager.
The problem seems to be that unlike other network device drivers I
checked, zd1201 does not do a SET_NETDEV_DEV(), which makes it so a
"device" symlink is created under /sys/class/net/wlan0.
With the following patch the device symlink shows up, and now I am
happily using NetworkManager to control the adapter:
$ ls -l /sys/class/net/wlan0
total 0

adds new module parameter "devid" that points to a string with format
"device_name:vendor_id:device_id:flags". if provided at module load
time, this string is being parsed and a new entry is created in
usb_dev_id[] and pegasus_ids[] so the new device can later be recognized
by the probe routine. this might be helpful for someone who don't
know/wish to build new module/kernel, but want to use his new usb-to-eth

This updates the handling of power state for USB interfaces.
- Formalizes an existing invariant: interface "power state" is a boolean:
ON when I/O is allowed, and FREEZE otherwise. It does so by defining
some inlined helpers, then using them.
- Adds a useful invariant: the only interfaces marked active are those
bound to non-suspended drivers. Later patches build on this invariant.
- Simplifies the interface driver API (and removes some error paths) by
removing the requirement that they record power state changes during
suspend and resume callbacks. Now usbcore does that.
A few drivers were simplified to address that last change.

Addresses some small bugs in the pegasus ethernet-over-USB driver.
Specifically, malformed long packets from the adapter could cause a kernel
panic; the interrupt interval calculation was inappropriate for high-speed
devices; the return code from read_mii_word was tested incorrectly; and
failure to unlink outstanding URBs before freeing them could lead to kernel
panics when unloading the driver.

This wraps up the conversion of the "usbnet" driver structure, by
moving the Prolific PL-2201/2302 minidriver to a module of its own.
It also includes some minor cleanups to the remaining "usbnet" file,
notably removing that long changelog at the top.
Minor historical note: Linux 2.2 first called the driver for
this hardware "plusb".

This adds host-side RNDIS support to the "usbnet" driver, so Linux can talk
to various devices (often based on WinCE) that otherwise only Windows could
talk to.
Tested with little-endian Linux talking to a Linux-USB Ethernet/RNDIS based
peripheral. This also includes updates from Eddie C. Dost <ecd@brainaid.de>
for big-endian SPARC Linux talking to a Nokia 9500 Communicator.
It's still marked as EXPERIMENTAL because this code is so young. This
ought to let Linux to work with various cable modems that previously
would have been "Windows Only".

As with the "cdc_subset" and "asix" drivers, this just moves the net1080
support into its one driver module. In this case there's a small bit of
extra cleanup involved, moving some funky framing logic into the tx_fixup()
routine (resolving a long overdue FIXME).
Minor historical note: "usbnet" started out as "net1080", then got
generalized to make it easier for other network drivers to reuse the
urb queueing and fault management code here.

This patch moves the ASIX AX8817x driver into its own file, just using
the "usbnet" infrastructure as a utility library.
- As with "cdc_subset" this involved minor Kconfig/kbuild tweaks,
moving code from one file to another, and exporting a few functions.
- This includes updates from Jamie Painter to add (and use) a new hook
to handle the different maximum transfer sizes for rx and tx sides.
- Also from Jamie, some bugfixes:
* MDIO byteorder (to address some PPC media negotiation problems);
* Force alignment at key spots when using ax88772 framing (on some
embedded hardware, the network stack will break otherwise);
* Address some link reset problems.
It also makes this driver use the standard (5 seconds vs half second)
control timeouts used elsewhere in USB; and wraps a few lines before
the 80th column (which previously needed it).

This patch creates the first of several separate "minidriver" modules
for "usbnet". This one handles only the very simplest hardware, which
can be handled almost entirely by the "usbnet" core.
- Move device-specific bits into new "cdc_subset.c" driver,
shrinking "usbnet" by a bunch;
- Export the functions needed to support this minidriver
(with EXPORT_SYMBOL_GPL);
- Update Kconfig and kbuild accordingly.
This one handles about a dozen different device types, with the most
notable ones being Gumstix and most Linux-based PDAs (except Zaurus
running that ancient code from Sharp).

This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"
can be modules that just plug into the core.
- Remove some framing-specific code that cluttered the core:
* net->hard_header_len records how much space to preallocate;
now drivers that add their own framing (Net1080, GeneLink,
Zaurus, and RNDIS) will have smoother TX paths. Even for
the drivers (Zaurus, Net1080) that need trailers.
* defines new dev->hard_mtu, using this "hardware" limit to
check changes to the link's settable "software" mtu.
* now net->hard_header_len and dev->hard_mtu are set up in the
driver bind() routines, if needed.
- Transaction ID is no longer specific to the Net1080 framing;
RNDIS needs one too.
- Creates a new "usbnet.h" header with declarations that are shared
between the core and what will be separate modules.
- Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
means the keventd work should just shut itself down asap.
The core code is only about 1/3 of this large file. Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will
improve maintainability and shrink typical runtime footprints.

29 July 2005, Cambridge, MA:
This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK
flag from the Linux kernel. Mr. Stern explained, "This flag is a relic
from an earlier, less-well-designed system. For over a year it hasn't
been used for anything other than printing warning messages."
An anonymous spokesman for the Linux kernel development community
commented, "This is exactly the sort of thing we see happening all the
time. As the kernel evolves, support for old techniques and old code can
be jettisoned and replaced by newer, better approaches. Proprietary
operating systems do not have the freedom or flexibility to change so
quickly."
Mr. Stern, a staff member at Harvard University's Rowland Institute who
works on Linux only as a hobby, noted that the patch (labelled as548) did
not update two files, keyspan.c and option.c, in the USB drivers' "serial"
subdirectory. "Those files need more extensive changes," he remarked.
"They examine the status field of several URBs at times when they're not
supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag
is removed."
Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all
of Linux's USB drivers, did not respond to our inquiries or return our
calls. His only comment was "Applied, thanks."

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.
Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.
