+Test Case 7: Split ring virtio-pci driver reload test with CBDMA enabled
+========================================================================
+
+1. Bind one nic port and one cbdma port to igb_uio, then launch the vhost sample by below commands::
+
+    rm -rf vhost-net*
+    ./testpmd -c 0xF0000000 -n 4 --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,queues=1,dmas=[txq0@00:04.0]' -- -i --nb-cores=1 --txd=1024 --rxd=1024
+    testpmd>start
+
+2. Launch VM::
+
+    taskset -c 32-33 \
+    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/ubuntu2004_2.img  \
+     -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,macaddr=00:00:00:08:e8:aa,addr=1f -net user,hostfwd=tcp:127.0.0.1:6004-:22 \
+     -chardev socket,id=char0,path=./vhost-net -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
+     -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=on,csum=on,gso=on,guest_csum=on,host_tso4=on,guest_tso4=on,guest_ecn=on \
+     -vnc :12 -daemonize
+
+3. On VM1, set virtio device IP, send 10M packets from packet generator to nic then check virtio device can receive packets::
+
+    ifconfig [ens3] 1.1.1.2      # [ens3] is the name of virtio-net
+    tcpdump -i [ens3]
+
+4. Reload virtio-net driver by below cmds::
+
+    ifconfig [ens3] down
+    ./dpdk-devbind.py -u [00:03.0]   # [00:03.0] is the pci addr of virtio-net
+    ./dpdk-devbind.py -b virtio-pci [00:03.0]
+
+5. Check virtio device can receive packets again::
+
+    ifconfig [ens3] 1.1.1.2
+    tcpdump -i [ens3]
+
+6. Rerun step4 and step5 100 times to check event idx workable after driver reload.
+

+================================================================================================================
+
+1. Bind one nic port to igb_uio, then launch the vhost sample by below commands::
+
+    rm -rf vhost-net*
+    ./testpmd -l 1-17 -n 4 --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,queues=16,client=1,dmas=[txq0@80:04.0;txq1@80:04.1;txq2@80:04.2;txq3@80:04.3;txq4@80:04.4;txq5@80:04.5;txq6@80:04.6;txq7@80:04.7;txq8@00:04.0;txq9@00:04.1;txq10@00:04.2;txq11@00:04.3;txq12@00:04.4;txq13@00:04.5;txq14@00:04.6;txq15@00:04.7],dmathr=64' -- -i --nb-cores=16 --txd=1024 --rxd=1024 --rxq=16 --txq=16
+    testpmd>start
+
+2. Launch VM::
+
+    taskset -c 32-33 \
+    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=16,sockets=1 -drive file=/home/osimg/ubuntu2004_2.img  \
+     -monitor unix:/tmp/vm2_monitor.sock,server,nowait -net nic,macaddr=00:00:00:08:e8:aa,addr=1f -net user,hostfwd=tcp:127.0.0.1:6004-:22 \

+     -vnc :12 -daemonize
+
+3. On VM1, give virtio device ip addr and enable vitio-net with 16 quques::
+
+    ifconfig [ens3] 1.1.1.2           # [ens3] is the name of virtio-net
+    ethtool -L [ens3] combined 16
+
+4. Send 10M different ip addr packets from packet generator to nic, check virtio-net interrupt times by below cmd in VM::
+
+    cat /proc/interrupts
+
+5. After two hours stress test, stop and restart testpmd, check each queue has new packets coming::
+
+    testpmd>stop
+    testpmd>start
+    testpmd>stop
+
