Subject: [PATCH v2 10/23] ath9k: Fix offchannel flush timeout
Date: Fri, 17 Oct 2014 07:40:17 +0530 [thread overview]
Message-ID: <1413511830-5536-11-git-send-email-sujith@msujith.org> (raw)
In-Reply-To: <1413511830-5536-1-git-send-email-sujith@msujith.org>
From: Sujith Manoharan <c_manoha@qca.qualcomm.com>
An offchannel operation also needs to have
a flush timeout that doesn't exceed the NoA
absence duration of a GO context, so use
channel_switch_time. The first offchannel
operation is set a flush timeout of 10ms since
channel_switch_time will be zero.
