So i don't get this. MDIO is just a bus, two lines. It can have up to
32 devices on it. The bus master should not need to have any idea what
devices are on it, it just twiddles the lines as requested.

Why does it need to know the external PHY address? In general, the
only thing which needs to know the PHY address is phylib.
