ath9k_htc: Fix BSSID calculation
The BSSID/AID has to be set for the first associated station interface. Subsequent interfaces may move out of assoc/disassoc status, in which case, the BSSID has to be re-calculated from the available interfaces. Also, ANI should be enabled or disabled based on the current opmode. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
