ath9k_hw: define modules to get/set Antenna diversity paramaters
these are the two important modules that will be called by the antenna diversity algorithm module in the rx. this will continuosly configure the hardware based on the current diversity status obtained from the algorithm Cc: Gabriel Tseng <Gabriel.Tseng@Atheros.com> Cc: Senthilkumar Balasubramanian <Senthilkumar.Balasubramanian@Atheros.com> Signed-off-by: Mohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: John W.
