Not necessarily. All that is needed is an external phy. Linux does not
care what MDIO bus that phy hangs off. It could be the same MDIO bus
as the switch, or some other MDIO bus. It is likely that port 5 is the
CPU port, but it does not have to be.

Great. I hope that will help determine if we can merge 6060 into 6xxx.
