[PATCH] rt2x00: Remove duplicate code in MAC & BSSID handling
The various drivers contained duplicate code to handle the MAC and BSSID initialization correctly. This moves the address copy to little endian variables to rt2x00config. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
