Subject: [PATCH] mac80211: don't handle filtered frames within a BA session
|
|
|
|
When running a BA session, the driver (or the hardware) already takes
|
|
care of retransmitting failed frames, since it has to keep the receiver
|
|
reorder window in sync.
|
|
|
|
Adding another layer of retransmit around that does not improve
|
|
anything. In fact, it can only lead to some strong reordering with huge
|
|
latency.
