SiS962 or SiS963 model, use EEPROM to store MAC address. And EEPROM is shared by LAN and 1394. When access EEPROM, send EEREQ signal to hardware first and wait for EEGNT. If EEGNT is ON, EEPROM is permitted to be access by LAN, otherwise is not. After MAC address is read from EEPROM, send EEDONE signal to refuse EEPROM access by LAN. The EEPROM map of SiS962 or SiS963 is different to SiS900. The signature field in SiS962 or SiS963 spec is meaningless. MAC address is read into @net_dev->dev_addr.
