ifdown works when the interface is connected, some logical interface is
configured and ifupdown knows to tear it down when ifdown is called
interactively and not by the user.

If the interface is just roaming, and then gets removed from the system,
that would require a hotplug script to do something like:
`wpa_action $IFACE check && wpa_action $IFACE down' or so I guess.
