Man bpf does have info you should check out.

The Berkeley Packet Filter bfp comes all ready installed on FBSD.
It's used in interactive mode. I do not know if there is
documentation on it. Man bfp has nothing.

Maybe you should ask the questions list how do you find the
documentation on bfp.

Or better yet explain why or what you are trying to accomplish using
bfp, maybe someone has better way of doing it.
