Please remove this code.  If we let you do it, we have to let everyone
else do it too, and that's something we don't want to do.

There are other ways you can handle this, for example have your board
firmware properly program the MAC address into the card at power-on,
and then have the driver here look in the MAC address registers to see
if a valid ethernet address has been left there.
