From: Senthil Balasubramanian Date: Tue, 27 Jul 2010 13:46:31 +0000 (+0530) Subject: ath9k: Introduce bit masks for valid and valid_single_stream. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f63b340d1bab58aac07ae1b528d58a73b76b0970;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
