ath/ath9k: Replace common->splitmic with a flag
Replace common->splitmic with ATH_CRYPT_CAP_MIC_COMBINED flag. splitmic has to be used when the ATH_CRYPT_CAP_MIC_COMBINED capability flag is not set. Signed-off-by: Bruno Randolf <br1@einfach.org> Acked-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
