At some point, it would be good for the cpsw driver to be moved to the
DSA subsystem, a lot of these tiny little details, like how to attach
the PHY to the internal, external, fixed MDIO bus have been solved
already using standard DT bindings. This leaves you with the fun part:
how to program your switch such that it works in response to the
networking stack sollicitations (bridge, VLAN, ethtool etc.).
