+================
+Vhost PMD xstats
+================
+
+This test plan will cover the basic vhost pmd xstats case and will be worked 
+as a regression test plan. In the test plan, we will use vhost as a pmd port 
+in testpmd. 
+
+Test Case1: xstats based on packet size
+=======================================
+
+flow: 
+TG-->NIC-->>Vhost TX-->Virtio RX-->Virtio TX-->Vhsot RX-->NIC-->TG
+
+1. Bind one physical port to igb_uio, then launch the testpmd
+
+2. Launch VM1 with using hugepage, 2048M memory, 2 cores, 
+   1 cockets ,1 virtio-net-pci::
+    taskset -c 6-7 qemu-system-x86_64 -name us-vhost-vm1 -cpu host -enable-kvm 
+    -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,
+    share=on -numa node,memdev=mem -mem-prealloc -smp cores=2,sockets=1 -drive 
+    file=/home/osimg/ubuntu16.img -chardev socket,id=char0,path=./vhost-net 
+    -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=1 
+    -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=off,mq=on 
+    -netdev tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device rtl8139,
+    netdev=ipvm1,id=net0,mac=00:00:00:00:10:01 -localtime -vnc :10 -daemonize
+   
+3. On VM1, run testpmd
+
+4. On host, testpmd, set ports to the mac forward mode
+   
+    testpmd>set fwd mac
+    testpmd>start tx_first
+
+5. On VM, testpmd, set port to the mac forward mode
+   
+    testpmd>set fwd mac
+    testpmd>start
+	
+6. On host run "show port xstats all" at least twice to check the packets number
+
+7. Let TG generate different size of packets, send 10000 packets for each packet 
+   sizes(64,128,255, 512, 1024, 1523), check the statistic number is correct
+
+8. On host run "clear port xstats all" , then all the statistic date should be 0
+
+Test Case2: xstats based on packet types
+========================================
+
+Similar as Test Case1, all steps are similar except step6,7: 
+ 
+6. On host run "show port xstats all" at least twice to check the packets type:
+
+7. Let TG generate different type of packets, broadcast, multicast, ucast, check 
+   the statistic number is correct 
+
+8. On host run "clear port xstats all" , then all the statistic date should be 0
+
+Test Case3: stability case with multiple queues
+===============================================
+1. No need bind any physical port to igb_uio,then launch the testpmd
+
+2. Launch VM1, set queues=2, vectors=2xqueues+2, mq=on, with using hugepage,
+   2048M memory, 2 cores, 1 cockets ,1 virtio-net-pci::
+    taskset -c 6-7 qemu-system-x86_64 -name us-vhost-vm1 -cpu host -enable-kvm 
+    -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,\
+    share=on -numa node,memdev=mem -mem-prealloc \
+    -smp cores=2,sockets=1 -drive file=/home/osimg/ubuntu16.img  \
+    -chardev socket,id=char0,path=./vhost-net \
+    -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=1 \
+    -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=off,mq=on \
+    -netdev tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device rtl8139,
+    netdev=ipvm1,id=net0,mac=00:00:00:00:10:01 -localtime -vnc :10 -daemonize
+
+3. On VM1, run testpmd
+
+4. On host, testpmd, set ports to the mac forward mode
+   
+    testpmd>set fwd io retry
+    testpmd>start tx_first 8
+
+5. On VM, testpmd, set port to the mac forward mode
+   
+    testpmd>start
+
+6. Send packets for 30 minutes, check the Xstatsa still can work correctly
+   testpmd>show port xstats all
