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
