Log:
Turn off route header processing for now due to issues pointed out
by Philippe Biondi and Arnaud Ebalard. This is a temporary fix
until more discussion can be had on the exact risks involved in
allowing source routing in IPv6

I forgot to mention (and not George's issue) is that a bit of work is
needed on ipfw for IPv6 data types. I have hit several issues which I
worked around, but, ATM, it can't differentiate between RH0 and RH2 in a
filter.
Just a five-minute-o-patch. I have not even compile time tested it.
'route' will still match any routing header.
'rh0' should match rh0, and 'rh2' should match rh2.

Let me know if it works (or not;-)
Boy, that was fast. Unfortunately, it does not compile:

*** Error code 1
Stop in /usr/src/sbin/ipfw.c
compiles here; make sure it picks up the new header. Doing a full
buildworld is easiest;-)
