What is the difference between the ID table (IDT) and the SROM? And why do we
not program the ID table if we have SROM?
BTW, where is the code that programs the MAC address *into* the IDT/SROM? All
we have is code that reads *from* the IDT/SROM. On the 8610, the MAC address is
stored in I2C EEPROM (address 0x57), and so U-Boot will need to copy that into
the IDT/SROM *before* this driver runs.
