Subject: [PATCH 70/78] wl18xx: add module parameter to force SISO 20MHz
Date: Thu, 10 May 2012 12:14:15 +0300 [thread overview]
Message-ID: <1336641263-5761-71-git-send-email-arik@wizery.com> (raw)
In-Reply-To: <1336641263-5761-1-git-send-email-arik@wizery.com>
From: Luciano Coelho <coelho@ti.com>
In some cases it may be useful to force narrow-band SISO channels.
Add a new value to the ht_mode module parameter to force the device to
operate in SISO 20MHz.
