 Subject: [PATCH] BPF Just-In-Time compiler
 
 I ported 'jitter' from WinPcap 3.1 to FreeBSD for i386 and wrote amd64
 support:
 
 http://people.freebsd.org/~jkim/bpf_jitter.diff
 
 I didn't do much testing but it seems working pretty well for me so
 far. ;-)
 
 You need the following line in the kernel configuration:
 
         options BPF_JITTER
 
 You can turn off filtering through JIT-compiled filter by setting:
 
         sysctl net.bpf.jitter.enable=0
 
 If you are using very complex filters, it may be useful for you.
 
 Caveats are:
 
 1.  BIOCSETWF is not supported.
 2.  bpf_mtap2() is not supported and bpf_mtap() is partially
 supported.
 3.  amd64 and i386 only.
 4.  Intel assembler notation. :-(
 5.  ...
 
 Testing, benchmarking, reviews, comments, complaints, patches for
 other architectures, etc, all welcome.
 
 Cheers,
 
 Jung-uk Kim
