    This would be acceptable. It only needs a simple script to poke the correct
    value, and that could be easily integrated into vendor scripts. The general
    idea of being able to have a callback to userspace is okay but we'd like
    something lighter weight for live migration, which is typically done only
    within the scope of a single layer-2 network and hence all that is really
    required is the gratuitous ARP to kick the switch hardware.
