I think it is right. When we do .sleep, we force both links down and
then schedule a network change. When we do .wake, we don't bring the
devices back up, but we do test for if networks are available.  On
wired, we never get back that it's available, because link state is only
reported if the device is up.  For wireless, we have to initiate a scan,
and that brings the device up.
