| |
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.
