        May be using multicast MACs for non-multicast VIPs and with
ALLMULTI enabled (or PROMISC, who cares on switched hub)? Because I
don't see how uploading multicast filters will work with all net
drivers. Of course, I'm newbie in the multicasting but may be there
are other reserved MACs for multicasting except 01:00:5E?
