Re: IPv6 + tunnel + ESP + IPcomp?

I believe the first one (NetBSD) is wrong:

it should be 2900 a970 (i.e., next-header|flags|cpi where the CPI is below:

> 2001:db8:1:2::45 2001:db8:1:2::23
>         ipcomp mode=any spi=43376(0x0000a970) reqid=16390(0x00004006)

which this, on linux, does contain:

>   c9a6 5a98 0000 001d (SPI+SEQ) 2900 96c4

src 2001:db8:1:2::45 dst 2001:db8:1:2::23
proto comp spi 0x000096c4 reqid 1 mode tunnel
