+DPDK Vhost loopback performance for virtio_user
+===============================================
+
+This test plan will cover the loopback performance test cases based virtio_user
+
+Test Case 1: DPDK loopback performance on mergeable path
+========================================================
+
+Flow: 
+Vhost --> Virtio--> Vhost
+
+1. First build the dpdk, don't bind any port to igb_uio
+
+2. Start up vhost user side using testpmd::
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x3000 -n 4 --socket-mem 1024,1024  \
+	--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i
+
+3. Start up virtio_user side using testpmd:
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xc000 -n 4 \
+	--socket-mem 1024,1024 --no-pci --file-prefix=virtio \
+	--vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net -- \
+	-i --disable-hw-vlan-filter
+
+4. At Vhost side, set it to mac fwd mode
+    testpmd>set fwd mac retry
+	testpmd>start tx_first 32 
+
+5. At Virtio side, set it to mac fwd mode
+    testpmd>set fwd mac retry
+	testpmd>start tx_first 32 
+	
+6. At the Virtio side, check the throughput
+    testpmd>show port stats all
+	
+Test Case 2: DPDK loopback performance on normal path
+=====================================================
+Flow: 
+Vhost --> Virtio--> Vhost
+
+1. First disbale the mergebale by modify the file /drivers/net/virtio/virtio_ethdev.h
+        1u << VIRTIO_NET_F_CTRL_VLAN     |     \
+    -   1u << VIRTIO_NET_F_MRG_RXBUF     |     \
+        1ULL << VIRTIO_F_VERSION_1
+
+2. Build the dpdk, don't bind any port to igb_uioStart up vhost user side using testpmd::
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x3000 -n 4 --socket-mem 1024,1024  \
+	--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i
+
+3. Start up virtio_user side using testpmd, using txflaf=0xf00:
+    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xc000 -n 4 \
+	--socket-mem 1024,1024 --no-pci --file-prefix=virtio \
+	--vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net -- \
+	-i --txqflags=0xf00 --disable-hw-vlan-filter
+
+4. At Vhost side, set it to mac fwd mode
+    testpmd>set fwd mac retry
+	testpmd>start tx_first 32 
+
+5. At Virtio side, set it to mac fwd mode
+    testpmd>set fwd mac retry
+	testpmd>start tx_first 32 
+	
+6. At the Virtio side, check the throughput
+    testpmd>show port stats all
+	
+Test Case 3: DPDK loopback performance on vecotr path
+=====================================================
+Flow: 
+Vhost --> Virtio--> Vhost
+
+1. First disbale the mergebale by modify the file /drivers/net/virtio/virtio_ethdev.h
+        1u << VIRTIO_NET_F_CTRL_VLAN     |     \
+    -   1u << VIRTIO_NET_F_MRG_RXBUF     |     \
