Subject: ath10k: wake up offchannel queue properly
From: Michal Kazior <[email protected]>
commit 3a73d1a6f22bf13044056543ad43b2a304ee0022 upstream.
Once HTT Tx queue got full offchannel queue was
stopped and never woken up again. This broke, e.g.
P2P. This could be reproduced after running a lot
of traffic enough to saturate 100% of the driver
Tx queue and then trying to send offchannel
traffic.
