SVN rev 210474 on 2010-07-25 17:40:48Z by rpaulo
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.
