ath9k: Introduce bit masks for valid and valid_single_stream.
replace valid and valid_single_stream in rate table with bit masks and reorganize the code so adding 3x3 rate control would be easier. Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
