[PATCH] DM9000 - check for MAC left in by bootloader



The DM9000 driver does not deal with the case
where there is no serial EEPROM to store the
configuration, and the bootloader has placed
an MAC address into the device already.

If there is no valid MAC in the EEPROM, read
the one already in the chip and check to see
if that one is valid.
