[PATCH] mac80211: make workqueue freezable

[Johannes Berg <johannes@sipsolutions.net>]

This patch makes the mac80211 workqueue freezable making it
interact a bit better with system suspend and not try to ping
the AP while the hardware is down.

This doesn't really help with implementing proper suspend in
any way but makes some bad things trigger less.

I'm not sure whether we should put this into 2.6.26 or not, while it
might help a bit it doesn't really do much over what the tx bugs finder
already does except avoid sending out the packets that froze b43 in the
first place...

Ivo, you might consider using =EF=BB=BFcreate_freezeable_workqueue for =
your
rt2x00 patch though.
