 Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched,
 virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed.
-This feature test need cover different rx/tx paths with virtio 1.0 and virtio 1.1, includes virtio 1.0 mergeable, normal, vector_rx, inorder no-mergeable, inorder mergeable path and virtio 1.1 mergeable, normal path.

+===============================================================================================
+
+1. launch vhost as client mode with 2 queues::
+
+    rm -rf vhost-net*
+    ./testpmd -c 0xe -n 4 --socket-mem 1024,1024 --legacy-mem --no-pci --file-prefix=vhost \

+    >set fwd mac
+    >start
+
+2. Launch virtio-user as server mode with 2 queues::
+
+    ./testpmd -n 4 -l 5-7 --socket-mem 1024,1024 --legacy-mem --no-pci --file-prefix=virtio \

+
+3. Quit vhost side testpmd, check the virtio-user side link status::
+
+    testpmd> show port info 0
+    #it should show "down"
+
+4. Relaunch vhost and send packets::

+5. Check the virtio-user side link status and run below command to get throughput,verify the loopback throughput is not zero::

+
+6. Check each RX/TX queue has packets::
