Reading the EEPROM to learn the station address doesn't seem to work

Browse Source 
on boards with VIA gigE controllers that are embedded in VIA chipsets.
Presumably, they don't have an external EEPROM and store the MAC
address somewhere else. To get around this, force an autoload and
read the station address from the RX filter registers instead.
This has been tested to work on both embedded and standalone
controllers.
