MII phy_ports are not meant to be connected directly to a link partner.
They are meant to feed into some media converter devices, so far we only
support SFP modules for that.

We have information about what MII they can handle, however we don't
store anything about whether they are currently connected to an SFP
module or not. As phy_port aims at listing the front-facing ports, let's
store an "occupied" bit to know whether or not a MII port is currently
front-facing (i.e. there's no module in the SFP cage), or occupied (i.e.
there's an SFP module).

To me, "front-facing" refers to things like user ports on a switch versus CPU-
facing ports, I don't find it intuitive to use it to qualify a port's state of 
being connected to an empty SFP cage.

Why not use something like "vacant" or "empty" instead?

Thanks,
