ath9k: Configure RX filter for multi-BSSID broadcast
Allow RX filter to pass through all broadcast/multicast frames (i.e., no BSSID filtering) if virtual interfaces are used. Software filtering will be used in this case to drop broadcast/multicast frames for foreign BSSIDs. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
