Subject: [PATCH 05/13] iwlwifi: mvm: rs: increase stay in column timeout
Date: Mon,  2 Dec 2013 22:59:17 +0200	[thread overview]
Message-ID: <1386017965-13641-5-git-send-email-egrumbach@gmail.com> (raw)
In-Reply-To: <529CF2D6.1080008@gmail.com>

From: Eyal Shapira <eyal@wizery.com>

Remain in the same Tx modulation (i.e. column) for a longer
time before starting a search cycle for a better modulation.
This has been shown to give better results.
Also change the name of the timeout define to better match its
description.
