This patch adds the ar9170 driver for Atheros 802.11n
USB hardware ("otus").
NOTES/TODO
* locks up RX part of the device after a while and the device
starts messing with the USB bus
(message will be "complete rx %p (0b, -75)")
* need to implement RF, TX power calibration based on EEPROM
values (maybe causing the RX hangs? doubt it)
* already needs some code cleanups
* use rate hw_value instead of huge switch statement
* implement configure_filter
* implement bss_config call
* implement beaconing
* implement hardware crypto
* implement AP mode
* implement mesh mode

I agree, Johannes is doing the right thing here, it doesn't need to be
in the staging tree at all.

And the required firmware has made it to the firmware tree:

just put it in /lib/firmware/

Ok, I'm happy to say that thanks to Stephen and Yuan-Gu who helped me
get the Atheros driver working on big-endian and usbmon, the driver now
seems to be stable, I've sent this email with it over a wpa link.

I get a 404 on the second patch.

I got annoyed with quilt, so now you can find the driver at
http://git.sipsolutions.net/ar9170.git

If this driver is not going in through wireless or any other tree, because it
still needs some work, maybe it is worth to get it to staging tree maintained
by Greg?

Better URL is
http://johannes.sipsolutions.net/patches/kernel/all/LATEST/NNN-ar9170.patch
because it automatically gives you the number.
Also, I just realised that you need two firmware files for that, I'm
working on getting those into the linux-firmware tree at
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=shortlog

Looks like the magic with NNN isn't working right yet...

No way. It _will_ go through the wireless tree, trust me, it's just not
ready yet. Meanwhile, Greg has the mess of a vendor driver.

I really don't think that is necessary. I don't forsee any problem w/
Johannes getting his driver merged.

This one works though:

And if you don't like http-git, use
git://git.kernel.org/pub/scm/linux/kernel/git/jberg/ar9170.git

In addition to that, you will want to apply this patch
http://johannes.sipsolutions.net/patches/kernel/all/LATEST/NNN-mac80211-fix-tasklet.patch
too because otherwise sometimes mac80211 will schedule a disabled
tasklet with the expected dead loop consequence, and then later will
even wait for it to finish... I'll submit this proper once I've figured
out why it's happening.
