Ouch!  Two problems:
   Your EEPROM is erased or unreadable.
       Your temporary station address is now "Linux" !
       This will work only if you have the only broken machine on your
       network. Please don't leave it like this.
   Your card hasn't been assigned an IRQ by the PCI BIOS.
       Read "The Solutions" section in

This part is good: the MII transceiver avoid a bunch of 21143-specific
problem that show up when you have a SYM (SYMbol mode) transceiver.

[[ Since so many EEPROM media tables were wrong, I put in code to search for
MII transceivers regardless of the EEPROM contents. ]]

No, but we have to figure out if your card has a blank EEPROM, or a new type
of EEPROM.   (I *really* hope that it's just blank.)
