Subject: [RFC] ibss: Added channel type in order to create HT IBSS
Date: Sun,  2 May 2010 16:12:08 +0200
Message-Id: <1272809528-11000-1-git-send-email-benoit.papillault@free.fr>
Sender: linux-wireless-owner@vger.kernel.org
List-ID: <linux-wireless.vger.kernel.org>

When joining an IBSS, the parameters can be used to create the IBSS. As
such, we need to know if the user wants to create an HT IBSS or not.
This is accomplish by passing the channel type (ie ht20, ht40- or
ht40+). Default is to create a non HT IBSS.
