2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------ From: Luis R. Rodriguez <[email protected]> commit cf3a03b9c99a0b2715741d116f50f513f545bb2d upstream. With AR9003 at about ~ 10 feet from an AP that uses RTS / CTS you will be able to associate but not not get data through given that the power for the rates used was set too low. This increases the power and permits data connectivity at longer distances from access points when connected with HT40. Without this you will not get any data through when associated to APs configured in HT40 at about more than 10 feet away.
