This feature is missing in the ar6000 driver. I thought it was there
already when I found WMI_SET_MAC_ADDRESS_CMDID in the source, but that
one is used for wake-on-wireless. It wouldn't be that hard to
implement, 2 new ioctls (set mac and reset mac) and another 6 bytes to
save the original mac address.
