The intent is to hide the netdev by default but have an > option to see it. I'm fine with having a link dump API to inspect the hidden netdev.

Perhaps a new set of sub-commands of, say, 'ip device'. -Siwei _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
