This is part of the hwilib already, so no need to add this one twice, see [1]
> Show an error if the MAC address is invalid.

If there is no valid MAC address in hwinfo.hex then the MAC will keep the one which is already programmed by the inital i210 firmware image. So there is no case where we end up with no MAC address at all, it will just be the default one. Therefor just notify in the log that the default MAC address will be used.
