	you keep asking (good) questions, but why?  will you plan to send
	some summary to somewhere, or put up onto web, to give feedback to
	people?  if you have no plan, i suggest you to do that.

	from within sys/netinet6/icmp6.c:icmp6_input(), icmp6_rip6_input()
	is called.  rtadvd(8) listens to raw IPv6 socket (IPPROTO_ICMPV6)
	and accepts data through the socket.
