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.
