Well, I am not particularly convinced we should expose the concept of
an "UFD group" at all. However, I think it would make a ton of sense
to show which interfaces are downlinks to an uplink interface, and
which interface is an uplink for a downlink interface, all based on
the relation expressed with BindCarrier=.

For this example, I think networkctl should show:

    # networkctl status sw0p10
    ...
    Carrier Bound By: sw0p49
                      sw0p51
                      sw0p5
                      sw0p7
    ...
    # netwokctl status sw0p49
    ...
    Carrier Bound To: sw0p10
    ...

If that makes sense?
