Just took a quick look through sys/dev/ic/hme.c.  Looks like the multicast
address filter is never enabled (HME_MAC_RXCFG_HENABLE) in NetBSD; unless
I'm missing something (altogether possible, since I'm browsing netbsd via
cvs web).  The multicast filter on hme definately works, though.  I had a
ss5 with a quad hme acting as an OSPF router under OpenBSD up until a few
months ago.
