- 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.
