commit: 01d4ab96d2e7fceaad204e5a8710ce34e229b8c5 From: Felix Fietkau <[email protected]> Date: Fri, 15 Mar 2013 16:18:44 +0100 Subject: ath9k: limit tx path hang check to normal data queues
The beacon and multicast-buffer queues are managed by the beacon tasklet, and the generic tx path hang check does not help in any way here. Running it on those queues anyway can introduce some race conditions leading to unnecessary chip resets. Cc: [email protected] Signed-off-by: Felix Fietkau <[email protected]> Signed-off-by: John W.
