If you're going to CC: netdev on your first two patches that expose infrastructure, you should CC: us on the third patch too so we can see how in the world you're using this stuff. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This is needed for C/R. For checkpoint, we need to be able to follow the link from one veth device to its peer.
