ath5k: set mac address in add_interface
Configure the mac address in add_interface and clear it in remove_interface so that users can change the mac address to something other than the one in the eeprom. Also avoid setting it at attach time so that we won't ack packets until fully set up. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
