Subject: [02/11] ath9k_hw: fix parsing of HT40 5 GHz CTLs
Date: Sat, 18 Sep 2010 11:44:58 -0700	[thread overview]
Message-ID: <20100918184621.064344908@clark.site> (raw)
In-Reply-To: <20100918184651.GA14224@kroah.com>

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Luis R. Rodriguez <lrodriguez@atheros.com>

commit 904879748d7439a6dabdc6be9aad983e216b027d upstream.

The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.
