is assumed to be in host byteorder during the input(?) path. NetBSD
keeps ip_off and ip_len in network order. Add (or remove) byteswaps
accordingly. TCP over fast_ipsec now works with PMTU, as well as without.
Fast-IPsec is a rework of the OpenBSD and KAME IPsec code, using the
OpenCryptoFramework (and thus hardware crypto accelerators) and
numerous detailed performance improvements.
This import is (aside from SPL-level names) the FreeBSD source,
imported ``as-is'' as a historical snapshot, for future maintenance
and comparison against the FreeBSD source. For now, several minor
kernel-API differences are hidden by macros a shim file, ipsec_osdep.h,
which (aside from SPL names) can be targeted at either NetBSD or FreeBSD.
