mii_ethtool_gset() does not return any errors. We can make it return
void to simplify error checking in drivers, that rely on return value
of this function.

Please squash the changes or invert the order.

Please invert the order. You will need slightly different justification for the
PCH GBE patch. Feel free to add my
