+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 | \

+ 1ULL << VIRTIO_F_VERSION_1
