Thanks for the pointer; I didn't know this existed.
The tool is not much good for IPv6 though:
[root@ws-6gw sendip]# ./sendip ::1
Couldn't get destination host: gethostbyname2(): Success
[root@ws-6gw sendip]# ./sendip ::1 -A inet6
Couldn't setsockopt IP_HDRINCL: Protocol not available
(I'm certain this can be gotten to work, but didn't seem too encouraging)
.. not to mention the terrible state of documentation (compare hidden
code cases like '-A', usage() and the manpage).
Also, this isn't able to formulate too specific IPv6/ICMPv6 packets; for
example, it isn't possible to stack a few extension headers, or specify
ICMP neighbour discovery parameters.
Ie. might be good for basic testing if it worked ok.

As davem suggested, I ported v6test to use PF_PACKET. It's really dirty
but would appear to work. We'll see.
