Subject: [PATCH 6.0] wifi: mt76: fix reading current per-tid starting sequence number for aggregation
Date: Fri, 26 Aug 2022 20:23:29 +0200 [thread overview]
Message-ID: <20220826182329.18155-1-nbd@nbd.name> (raw)
The code was accidentally shifting register values down by tid % 32 instead of
(tid * field_size) % 32.
Cc: stable@vger.kernel.org
Fixes: a28bef561a5c ("mt76: mt7615: re-enable offloading of sequence number assignment")
