mac80211: MBSSID support in interface handling
Configure multiple BSSID and enhanced multi-BSSID advertisement (EMA)
parameters in mac80211 for AP mode.
For each interface, 'mbssid_tx_vif' points to the transmitting interface of
the MBSSID set. The pointer is set to NULL if MBSSID is disabled.
Function ieee80211_stop() is modified to always bring down all the
non-transmitting interfaces first and the transmitting interface last.
