| Subject: [PATCH] mac80211: don't handle filtered frames within a BA session |
| |
| commit 890030d3c425f49abaa4acf60e20f288b599f980 upstream. |
| |
| 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. |
