I've got two use cases. One is 'nova baremetal' - where we are
modelling the physical world directly using Neutron. So you'd want to
model both physical ports with their unique MACs and the fact they are
bonded etc.

A related one is virtual IPs for HA for nova baremetal, but I'm not
sure having that modelled as a /port/ makes sense, rather a second IP
on a port.
