Subject: [PATCH V2 10/27] ath9k_hw: Find the maximum number of chains that hw supports
Date: Thu, 2 Dec 2010 03:06:54 -0800	[thread overview]
Message-ID: <1291288031-3409-11-git-send-email-vasanth@atheros.com> (raw)
In-Reply-To: <1291288031-3409-1-git-send-email-vasanth@atheros.com>

Have it in ah->caps. This will be used during various
calibrations.
