Or:
1. Relaxed, where interfaces with the same names and matching option values if
present for both interfaces are considered to be the same interfaces;
2. Strict, where all interfaces in all input files are considered to be
distinct even if they have matching names and attributes, with a matching file
as an option.
(This also raises the question of interfaces changing their addresses over the
course of a capture, which I'll have to raise on the pcap-ng mailing list....)
