MII phy_ports are not meant to be connected directly to a link partner.
They are meant to feed into some media converter devices that will

In the case an MDI phy_port is backed by an MII port (e.g. a SFP
module's port, backed by the SFP cage port), let's keep track of the
port id of the MII port backing it.
