MAC ID Address [15:0].
This field defines lower address bit15 to bit0 of MAC. The MACID0, MACID1
and MACID2 combine into 48-bit MAC address. The MAC address format is
[47:0] = {MACID2[15:0], MACID1[15:0], MACID0[15:0]}. If the EEPROM is
attached, this field will be auto-loaded from EEPROM after hardware reset.
