// A display filter, distinct from -f's capture filter (wireframe/filter.hpp):
// -f decides what's captured - and, combined with -w, what's written to
// disk. This decides what's shown, without touching either. Same
// distinction Wireshark draws between a capture filter and a display
// filter, just without the display filter's expression language - a
// plain case-insensitive substring match over the packet's summary line
// is enough for "find the packets mentioning this host/port", which is
// the actual use case.
