Here's a patch for FreeBSD 8.2/8.3 that fixes two different hardware checksumming problems with ipfilter: http://svn.m0n0.ch/wall/branches/freebsd8/build/patches/kernel/ip_fil_freebsd.c.patch (it's simply Pyun's patch from <http://www.freebsd.org/cgi/query-pr.cgi?pr=106438> combined with a patch for another HW checksum issue on UDP packets from <http://www.freebsd.org/cgi/query-pr.cgi?pr=166372>) - Manuel
