Max Laier	8de5b6f306	Use in_cksum_skip() to calculate in4_cksum instead of doing handrolled magic ... (that does not compile with !gcc). Moreover we get the benefit for all archs that have a hand optimized in_cksum_skip(). Submitted by: yongari Tested by: me (i386, extensivly), pf4freebsd ML (various)	2004-08-05 20:41:38 +00:00
Max Laier	2bbe8ffc9d	Bring diff from the security/pf port. This has code been tested as a port ... for a long time and is run in production use. This is the code present in portversion 2.03 with some additional tweaks. The rather extensive diff accounts for: - locking (to enable pf to work with a giant-free netstack) - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off - conversion from pool(9) to zone(9) - api differences etc. Approved by: bms(mentor) (in general)	2004-02-26 02:34:12 +00:00
