Subject: [PATCH v2 08/12] ath9k: fix clearing expired A-MPDU subframes in tx completion
Date: Tue, 6 Aug 2013 14:18:09 +0200 [thread overview]
Message-ID: <1375791493-83971-8-git-send-email-nbd@openwrt.org> (raw)
In-Reply-To: <1375791493-83971-1-git-send-email-nbd@openwrt.org>
When the tid aggregation state has been marked as inactive, free
completed tx packets immediately. When a new aggregation session has not
been initialized yet, the BAW checks do not recognize it as expired.
Might fix potential stalls in setting up a new aggregation session.
