Could you prefix your patches with "net: phy: " in the future to be
consistent with what is typically used?

Could we use a switch/case here? How about 10Mbits/sec and duplex are we
guaranteed to be full-duplex at e.g: 100 or 10Mbits/sec?

If these are 10GbE PHYs, should not we start defining a new features
bitmask here to reflect that accordingly? That way MAC
