Just out of curiosity, would a "match on any FT_IPV4 field" filter be useful, so that a packet that contains a given IPv4 address *anywhere* (or, at least, anywhere that it's an FT_IPV4 field, rather than, say, just a proto_tree_add_text() item) matches?

(And the same applies to IPv6 addresses and MAC-48 addresses and....)
