IPv6 integration to *BSD

in 1994/1995, there were 7 independent implementations in WIDE
each has only 1 maintainer, so the code could be wasted (manpower)
we decided to merge them into one as a joint effort - KAME project (1996-)

there are two other major implementations in the world - INRIA and NRL
KAME, INRIA and NRL sit together for integration
good amount of idea/code exchange
funding for INRIA and NRL work ends - so KAME (with INRIA/NRL contributions) is the last one standing

we have integrated IPv6 to *BSD around 1999-2000 timeframe
it is important that all *BSD IPv6 code is from the same origin
otherwise we have portability issues and maintenance headache
