Layer 2 only networking mode between rootless containers #298

I'm experimenting with the idea of layer 2 only rootless containers with the goal to test not IP protocols. Is there any way to use slirp4netns for connecting podman containers with raw network interfaces (without IP address). There is no need for external access.

No, because an unprivileged user does not have CAP_NET_RAW
