Hi, Maxime. I didn't actually look at the code, but I have a question. Does above text mean that with this change OVS will hang inside driver_register() or similar function until client is connected to dpdkvhostuser (server mode) port? If so, I think, we will not be able to support server mode in OVS anymore and will have to actually remove it. It's deprecated for a long time now, but I think it might still be in use by some people, especially for virtio-user usecase. Best regards, Ilya Maximets.
