This would be a documentation issue - the usage of nsPlugin is not covered in the README. I'll submit a patch by end of the day tomorrow to address it. The namespace code isn't mandatory, strictly speaking. It's not required at all when running the action tests, only with the filter tests as those need a specific device to be attached to. The actual problem is that the nsPlugin creates a veth pair using the names found in the config file (DEV0/DEV1) - but if you aren't using the plugin, then a port won't be created. The intention is that you'd create a port manually before starting the tests.
