The state of an on-demand interface must be visible, typically an
on-demand interface is in dormant state and goes to up while it is
in use and back to dormant after some time of inactivity. Further,
if the interface knows that a demand cannot be met it must announce
this so an alternative can be selected, typically this would be
the carrier/link state.
