It would be an added statistic for "ignored" UDP multicast datagrams,
incremented instead of UDP_MIB_NOPORTS. "UDP_MIB_IGNOREDMULTI" if you
will.
Similar in concept to what HP-UX NIC drivers would increment when they
received a frame for which there was no bound protocol - "inbound
unknown protocols" but not a drop
