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. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
