An unmodified eepro100.c driver _requires_ the EEPROM information to work
correctly.

You will have to either add the EEPROM to your design, or modify the driver
to hard-wire the transceiver and station address information.

You lose some of the i82559 features, such as wake-on-LAN, when you omit the
EEPROM.
