It depends. Some devices have EEPROM's that store the permanently
assigned MAC address, some have NVRAM for this, and yet other's put it
into the PCI ROM.
Some platforms that have real OF device trees often do not put the
permanent MAC address into the EEPROM or NVRAM even if it is
customary to do so on a particular device. The MAC has to be
obtained from the OF device tree.
