We now have a report of a system fitted with an EEPROM containing all zeros where we expect the MAC address to be, and we currently handle this as an error condition. Turns out, on this system the BIOS writes a valid MAC address to the NIC's MAC Station Address register, but we never try to read it because we return an error when we find the all- zeros address in EEPROM. This patch relaxes the error check and continues looking for a MAC address even if it finds an illegal one in EEPROM.
