Sorry for the large cross post, just seeing if someone is interested
in working on a wireless driver. The task would be to try to get
AR5523 USB driver up to speed with mac80211 from wireless-testing and
giving it a shot to fix remaining issues?

It seems to have compiled last for 2.6.23.

If you're interested please remove all lists and only leave

Hi,

I'm interested in working on this. I just posted to the Linux driver project a few days ago if I could work on the atheros USB devices. Please let me also know the USB device that uses the AR5523.

Thanks,
Purush

I have a few WPN111 Refurbed devices that are AR5523 based.  Apparently
there is a WPN111v2 that may or may not be otus supported, I can't confirm 
that.  Based on pictures from google and the devices I own, the AR5523 ones
are silver, and the Otus ones are white.  I'd be more than happy to test and
do what I can to try to help, but my time is limited, so I'm not up for 
taking the task onto my shoulders right now.

It seems that OpenBSD has driver for AR5523 (AR5005UG and AR5005UX) upstream. I
doubt that they would like to share their code with Linux - like dual licensing
GPL/BSD. Fortunately their documentation mentions which hardware includes those
chipsets, look here:

http://www.openbsd.org/cgi-bin/man.cgi?query=uath&sektion=4&apropos=0&manpath=OpenBSD+Current&arch=i386


Note that Atheros AR5007UG (alternatively known as AR2524/AR5524) is supported
by Linux zd1211rw driver.

I like to see the spec, even though I don't have a device (yet).

If you are asking me then sorry but I am not connected in any way with OpenBSD
and I do not have any hardware specifications :(
You should ask Atheros through Luis and also Damien Bergamini of OpenBSD.

Anyway I just realized that the partial Linux driver is actually a port of
OpenBSD driver with firmware extracted from Windows driver!

I hope that it is O.K. to have ISC licensed driver in GPL licensed kernel.

At the risk of starting another flame war with insane people, I'll
point-out that dual licensing is not necessary.  The BSD licensed
code is completely available to us.

I am not here to start a flame war of any sort,
yet if it sounded like that then I am terribly sorry. 
I came here to aid with a link to man page which includes a good list of
AR5005UG and AR5005UX based hardware which could be useful for the
developers.

Anyway thank you for the clarification.

Whether or not you are insane remains to be seen. :-)  Nevertheless,
you were _not_ the "insane people" I was alluding to above...

The following patch (no backwards compatibility) allows ar5523 to work on 
kernel 2.6.25, while I've started to look into the API changes required 
for 2.6.26 that isn't finished yet.

> If you're interested please remove all lists and only leave
> linux-wireless on the reply.

As long as ar5523 hasn't caught up with current wireless-testing HEAD, I'm
going to work on an out of tree version available here

	http://svn.berlios.de/svnroot/repos/fullstory/ar5523/trunk/
	svn://svn.berlios.de/fullstory/ar5523/trunk/

This contains only the *unchanged* driver files[1] required for ar5523, 
neither usb_probe.c (which only seems improve debugging), nor the required
device firmware uath-ar5523.bin. For the time being I intend to keep 
necessary changes in a separate quilt patch queue, to retain the copyright 
information for each change and to allow basic bisecting.

	http://svn.berlios.de/svnroot/repos/fullstory/ar5523/trunk/debian/patches/

For now, all of my changes concentrate on making ar5523 compatible with 
current wireless-testing, I haven't started with actually debugging the
driver yet.

Unfortunately I cannot make any promises regarding the potential time scale
of this porting, how far it'll get or if it will succeed at all, but I'd 
like to make a start and share the initial changes nevertheless. Hopefully 
this starts a broader effort to get this driver usable and eventually 
merged.

As the question about which devices are covered by ar5523 has already been
asked, I post the current annotated USB ID table for the driver[2] below.

static struct usb_device_id ar5523_id_table[] = {
	AR5523_DEVICE_UG(0x168c, 0x0001),	/* Atheros / AR5523 */

ar5523 is also known as ar5005UG (802.11b/g) or ar5006UX (802.11a/b/g), as
such the hardware[3] supports 54 MBit/s operations within the 2.4 GHz band 
(ar5006UX variants also in 5 GHz) and offers WPA support.

#
#    This patch gets rid of the if_id stuff where possible in favour of

#    structure is located at the end of the per-interface structure and
#    contains a variable length driver-use data area.
#
#    This has two advantages:
#     * removes the need to look up interfaces by if_id, this is better
#       for working with network namespaces and performance
#     * allows drivers to store and retrieve per-interface data without
