...and if we're not going to use the filter, we shouldn't let the user specify
it, as having a capture filter box fools the user into thinking it makes a
difference.

As such, doing bpf_filter() on the packets when reading from a pipe is probably
the right idea, if doable.  *HOWEVER*, doing the filtering in the program
writing to the pipe (or, if that program is getting its input from another
program, e.g. a tcpdump/WinDump run over ssh, doing it in *that* program -
i.e., doing itas early as possible in the pipeline) is *STILL* a good idea, as
per my previous comment.
