This surely needs VMState additions so the extra state can be passed
across migrations. It looks like the MDIO/PHY stuff from the etraxfs code
doesn't have any kind of state save/restore support, so you probably need
to first implement that in your new mdio/phy source file, and then refer
to it here.
