Description

From gerrit comment by laforge on https://gerrit.osmocom.org/c/libosmo-abis/+/21118 :

Actually, the fact that we only have a single pcap file for potentially multiple lines is a problem.

Classic pcap files do not offer a way to annotate each packet with information on which interface it was received, so you cannot distinguish traffic from multiple lines.

We need to address this in a generic way.
Ideally generating pcap-ng with interface descriptions, or by moving pcap generation to "per line".

But even a single line can contain multiple TEI / datalinks, and you want to somehow separate those.
