Use FF02:0:0:0:0:2:FF00::/104 prefix for IPv6 Node Information Group
Address. Although KAME implementation used FF02:0:0:0:0:2::/96 based on
older versions of draft-ietf-ipngwg-icmp-name-lookup, it has been changed
in RFC 4620.
The kernel always joins the /104-prefixed address, and additionally does
/96-prefixed one only when net.inet6.icmp6.nodeinfo_oldmcprefix=1.
The default value of the sysctl is 1.
ping6(8) -N flag now uses /104-prefixed one. When this flag is specified
twice, it uses /96-prefixed one instead.
