From 899ec57d57e8b42d4ca06a4882affceff37de7a0 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 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.
