Jason Andryuk noticed that at76_usb won't compile with current
wireless-testing tree. This is because net/ieee80211.h was missing.
net/ieee80211.h will be removed soon and at76_usb won't compile then that
happens. Preprare for that by using instead linux/ieee80211.h and copying
some structures not available.

Ping? This is still an issue in git head... Should probably go in via
the staging tree...

Ah, apologies. I forgot Greg uses that quilt tree and didn't find it
merged when I looked.

At least the patch is in Greg's staging directory:
http://kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-05-staging/staging-at76_usb-convert-to-use-linux-ieee80211.h.patch
I would assume that Greg pushes it forward at some point.
