simple patch for RIPng

[Goesta Smekal]

Dear List,

  as I stated earlier last November, there are some simple issues, which
prevent RIPng (aka IPv6 RIP) from working. Despite my rather basic
knowledge of C I endeavoured to try and fix it.

  So far, two things are fixed by my patch: the UDP port is set to 521
(instead of 520 for IPv4 RIP) and the version number set to 1.

  At least the protocol dissector of wireshark now accepts the packets
as correct RIPng messages (instead of "unknown protocol"). Anyway, my
virtualized test setup does not yet exchange routes. This may as well be
due to an error in my setup.

  Feedback is very appreciated ...

  Goesta
