I've checked in a patch based on it but that doesn't make as many
changes (some of the changes were unnecessary and broke stuff).

That's because nobody's written code to use "bpf_filter()" with the
libpcap expression when capturing from a pipe (perhaps because they
expected that the program piping *to* Ethereal would be doing the
filtering).
