I do not see why the MAC address should be runtime configurable. We have a cbfs file where the MAC address is retrieved from (hwinfo.hex). If this file is missing or there is no valid MAC address inside it (all 0xFF or 0x00) then the MAC will not be programmed and therefore keeps its original address. This message is just to make aware that there is not valid address in hwinfo.hex and is not a hard error.
