Should be in BIOS.because different MB use different MAC assigned in Factory.
But in MB design, it should use another SEEPROM to store that. So the BIOS or NIC get it.

Hello,
this patch sets 8111NIC's mac. The 48-bit mac address is
saved in OEM
ROM, in nic_init() the driver gets the mac address through register oem_mac_offset, and copy it to 8111NIC's PADR register.
Is it store is it own serial EEPROM or in the same ROM as BIOS? If it is stored in it won EEPROM, this code sould be in the kernel driver than BIOS.
