From 5eae6592e9bdc989151171828ee97e0ad9e1b1ac Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan Date: Tue, 9 Jun 2009 15:28:21 +0530 Subject: ath9k: Fix tx stuck when connected to aggr disabled HT AP This patch along with my previous patch in mac80211 "Fix the way ADDBA count..", fixes hang in tx when connected to an HT AP which rejects/times out on addba req. AGGR_ADDBA_PROGRESS should be cleared in aggr state when addba negotiation is terminated due to either addba response is timed out or addba is denied by the AP. With out clearing this bit, all frames are queued onto s/w queue for getting tx'd as aggr and will never be scheduled onto hw queue. Signed-off-by: Vasanthakumar Thiagarajan Signed-off-by: John W.
