3.6.11.2 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <n...@openwrt.org>
[ Upstream commit 01d4ab96d2e7fceaad204e5a8710ce34e229b8c5 ]
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.
