+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).
