mac80211: use multi-queue master netdevice
This patch updates mac80211 and drivers to be multi-queue aware and use that instead of the internal queue mapping. Also does a number of cleanups in various pieces of the code that fall out and reduces internal mac80211 state size. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
