Whatever they do (I bet it's nothing trivial): Everything that
complicates the pcap-based approach beyond a certain level (roughly the
one that is required for tap-based bridges) makes it unattractive. There
are alternatives (except for ancient Win2k IIRC), pcap just appeared to
be a cheap shortcut. But that turned out to be not true.
