BPF && Linux.

[Adam]

Question: 
	How Linux Kernel and BPF relate to each other:

	a) linux has BPF (I don't think so).
	b) Linux has own equivalent of BPF (part of NAT?)
	c) linux does not have anything like BPF 
	d) something else (if so, then what?)

Berkeley Packet Filter (BPF) of BSD kernel

BPF is described in paper ``The BSD Packet Filter: A New Architecture for
User-level Packet Capture''.
