[PATCH v2 3/4] mac80211: check if frame is really part of this BA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There was an an implicit assumption that any QoS data frame received
from a STA/TID with an active BA session was sent to this vif as part of
a BA.  This is not true if IFF_PROMISC is enabled and the frame was
destined for a different peer, for example. Don't treat these frames as
part of a BA from the sending STA.
