linux-stable.git/drivers/net/wireless/b43, branch linux-3.5.y Linux kernel stable tree b43: fix crash with OpenFWWF 2012-08-09T15:22:52+00:00 Johannes Berg johannes.berg@intel.com 2012-07-17T15:12:29+00:00 77a797164fa64308ead7da0b1898895979f10b15 commit 097b0e1bf18a00195cd89bb13565ddbc9b0df942 upstream. b43 with open firmware crashes mac80211 because it changes the number of queues at runtime which, while it was never really supported, now crashes mac80211 due to the new hardware queue logic. Fix this by detecting open vs. proprietary fw earlier and registering with mac80211 with the right number of queues.

commit 097b0e1bf18a00195cd89bb13565ddbc9b0df942 upstream.

b43 with open firmware crashes mac80211 because
it changes the number of queues at runtime which,
while it was never really supported, now crashes
mac80211 due to the new hardware queue logic.

Fix this by detecting open vs. proprietary fw
earlier and registering with mac80211 with the
right number of queues.
