mac80211: as a 4-addr station, do not receive packets for other stations
Since 4-addr frames completely override the source address which will
make it into the converted 802.3 frames, receiving frames for other
4-addr stations will confuse the bridging code.
To be able to handle traffic for all connected devices, the bridge
code will automatically turn on promiscuous mode, which triggers
this problem.
