Subject: [PATCH] Add AR9170 driver.
 The AR9170 configuration is only activated on kernel 2.6.28 and later, because the older kernel misses some needed functions.

Thanks applied and new tarball regenerated.

The patch commit log (which cannot be seen as the patch was attached)
only enables ar9170 for >= 2.6.28. If someone wants to get this on
2.6.27 you'll just have to backport the routines which fail to
compile. Patches welcomed of course.

v2.6.29-rc8-18695-g8fe80c6
wireless-testing latest tag:
master-2009-03-23
This is compat-release:
master-2009-03-23

One small note, Hauke, can you send these patches inline moving
forward? In this case it proved useful as the commit log had
information useful.

This may help, it has some example git send-email stuff:

I did some quick review on this. One of the routines I had heard fails
on 2.6.27 is usb_poison_anchored_urbs. This was added via 6a2839b.
This just adds the routine, the users are the drivers themselves. To
poison a URB it makes use of the extends the struct usb_anchor, so
directly porting it doesn't seem to make sense. Best bet seems to be
just backporting to not poison and do a replacement call.

Fun enough ar9170 is currently the only driver using this.

Hm, not sure if a no-op would do it.
