I fixed a bug in the multicast forwarding code, but it looks like I
never asked for a pullup. Read the cvs logs for
src/sys/netinet/ip_mroute.c, and see revision 1.95.  Apply that delta
to your 3.0 sources, rebuild, and please tell me if it works or not.
If the patch doesn't go in cleanly, send me the revised patch too for
the pullup request.
