MFC r209016, r209022:
 Some odd APs send beacons on the same TX queue as non-beacons. This breaks
 802.11 duplicate detection. Upon looking at the standard, we discover
 that 802.11-2007 says:
 "A receiving QoS STA is also required to keep only the most recent
 cache entry per<Address 2, TID, sequence-number>  triple, storing only
 the most recently received fragment number for that triple. A receiving
 STA may omit tuples obtained from broadcast/multicast or ATIM frames
 from the cache."

 To fix this, we just disable duplicate detection for multicast/broadcast
 frames.
