Karl Beldan c6e133277b mac80211: send {ADD,DEL}BA on AC_VO like other mgmt frames, as per spec 
ATM, {ADD,DEL}BA and BAR frames are sent on the AC matching the TID of
the BA parameters. In the discussion [1] about this patch, Johannes
recalled that it fixed some races with the DELBA and indeed this
behavior was introduced in [2].
While [2] is right for the BARs, the part queueing the {ADD,DEL}BAs on
their BA params TID AC violates the spec and is more a workaround for
some drivers. Helmut expressed some concerns wrt such drivers, in
particular DELBAs in rt2x00.

ATM, DELBAs are sent after a driver has called (hence "purposely")
ieee80211_start_tx_ba_cb_irqsafe and Johannes and Emmanuel gave some
details wrt intentions behind the split of the IEEE80211_AMPDU_TX_STOP_*
given to the driver ampdu_action supposed to call this function, which
could prove handy to people trying to do the right thing in faulty
drivers (if their fw/hw don't get in their way).
