Consider using PCAP/BPF interface or a wrapper like libnet....

pcap/bpf wouldn't do: i'd have to take care of neighbor-discovery and
routing myself. libnet would probably do, but.. hey! it's a simple ipv6
packet. and at this point, i'm curious about whether there's a limitation on
the addresses you can "forge" with sendmsg()

fwiw, linux seems to have an ipv6 version of ipv5}4 hdrinclude socket
option. that's nice, too.

thanx,
