99ef252d15 Add BPF Just-In-Time compiler support for ng_bpf(4). 
The sysctl is changed from net.bpf.jitter.enable to net.bpf_jitter.enable
and this controls both bpf(4) and ng_bpf(4) now.

055dc8e121 Add experimental BPF Just-In-Time compiler for amd64 and i386. 
Use the following kernel configuration option to enable:

	options BPF_JITTER

If you want to use bpf_filter() instead (e. g., debugging), do:

	sysctl net.bpf.jitter.enable=0

to turn it off.

Currently BIOCSETWF and bpf_mtap2() are unsupported, and bpf_mtap() is
partially supported because 1) no need, 2) avoid expensive m_copydata(9).

Obtained from:	WinPcap 3.1 (for i386)
