    Maybe we should be faking this out from our hotplug scripts in the
    control VM, although triggering this from user space is probably a bit
    of a pain. Regardless, the function can be removed from the driver if
    it's too distasteful: it's only a performance 'hack' to get network
    traffic more quickly redirected when migrating a VM between physical
    hosts. Things won't break horribly if it's removed.
