Subject: [PATCH AUTOSEL 5.10 02/13] mac80211: fix rx reordering with non explicit / psmp ack policy
Date: Wed, 18 May 2022 08:28:33 -0400 [thread overview]
Message-ID: <20220518122844.343220-2-sashal@kernel.org> (raw)
In-Reply-To: <20220518122844.343220-1-sashal@kernel.org>
From: Felix Fietkau <nbd@nbd.name>
[ Upstream commit 5e469ed9764d4722c59562da13120bd2dc6834c5 ]
When the QoS ack policy was set to non explicit / psmp ack, frames are treated
as not being part of a BA session, which causes extra latency on reordering.
Fix this by only bypassing reordering for packets with no-ack policy
