Dear Pavel,

Correct me if I'm wrong, but this read_macreg function seems to be
completely unused by the rest of the driver. Rather than changing the
signature to do error handling, maybe it would be better to just remove
it?

That is just my view though, would be interested to see what others
think - perhaps it could come in handy at some point.

Regards,
Phil
