From 897d7fd9b5f1bee657d000b882c642541bb2ba3e Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 6 Aug 2013 14:18:09 +0200 Subject: [PATCH] ath9k: fix clearing expired A-MPDU subframes in tx completion 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.
