That's correct.

For KAME, yes.  And as I explained in the previous message, the kernel
part implementation has already been incorporated to the NetBSD kernel.
The only missing part is the userland utility (ip6addrctl), which is
available in KAME snapshots and should be easily merged to NetBSD.

I don't understand how the (FAST_)IPSEC implementation relates to
RFC3484, but I don't know the answer anyway.
