From 890030d3c425f49abaa4acf60e20f288b599f980 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 22 Feb 2017 16:16:07 +0100 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.
