From 3a73d1a6f22bf13044056543ad43b2a304ee0022 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Thu, 6 Aug 2015 14:46:54 +0200 Subject: [PATCH] ath10k: wake up offchannel queue properly 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.
