+vhost/virtio-user pvp with 2M hugepage test plan
+================================================
+
+Description
+===========
+
+Before 18.05, virtio-user can only work 1G hugepage. After 18.05, more hugepage pages can be represented by single fd （file descriptor）file, so virtio-user can work with 2M hugepage now. The key parameter is "--single-file-segments" when launch virtio-user.
+
+Test Case1:  Basic test for virtio-user 2M hugepage
+===================================================
+
+1. Before the test, plese make sure only 2M hugepage are mounted in host.
+
+2. Bind one port to igb_uio, launch vhost::
+
+    ./testpmd -l 3-4 -n 4 --socket-mem 1024,1024 --file-prefix=vhost \
+    --vdev 'net_vhost0,iface=/tmp/sock0,queues=1' -- -i
+
+3. Launch virtio-user with 2M hugepage::
+
+    ./testpmd -l 5-6 -n 4  --no-pci --socket-mem 1024,1024 --single-file-segments --file-prefix=virtio-user \
+    --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,queues=1 -- -i
+
+
+3. Send packet with packet generator with different packet size,includes [64, 128, 256, 512, 1024, 1518], check the throughput with below command::
+
+    testpmd>show port stats all
