Does DPDK vhost-user support VIRTIO_F_NOTIFY_ON_EMPTY, the legacy interface reserved feature bit? (The 6.3 section in https://stefanha.github.io/virtio/vhost-user-slave.html) I'd see it set in VIRTIO_NET_SUPPORTED_FEATURES in vhost.h. So, will it cause an exception if we migrate the VM which uses vhost_net and enable VIRTIO_F_NOTIFY_ON_EMPTY? Look forward to hearing from you.
