Also, is there a solution, or plans for a solution, to address macvtap
interfaces that are set to 'promiscuous' mode?  It would seem fairly easy to
support this for interfaces that are simply trying to listen to the port
(e.g. Wireshark).  If the port was being used by something like a firewall
then the VEPA filtering doesn't work too well.
