Subject: [PATCH] mac80211: fix reordering of buffered broadcast packets
If the buffered broadcast queue contains packets, letting new packets bypass
that queue can lead to heavy reordering, since the driver is probably throttling
transmission of buffered multicast packets after beacons.
Keep buffering packets until the buffer has been cleared (and no client
is in powersave mode).
