+========================================================
+Vswitch sample test with vhost async data path test plan
+========================================================
+
+Description
+===========
+
+Vswitch sample can leverage DMA to accelerate vhost async data-path from dpdk 20.11. This plan test
+vhost DMA operation callbacks for DSA PMD and vhost async data-path in vhost sample.
+
+--dmas This parameter is used to specify the assigned DMA device of a vhost device. Async vhost-user
+net driver will be used if --dmas is set. For example –dmas [txd0@wq0.0,txd1@wq0.1,rxd0@wq0.2,rxd1@wq0.3]
+means use DMA channel wq0.0/wq0.2 for vhost device 0 enqueue/dequeue operation and use DMA channel
+wq0.1/wq0.3 for vhost device 1 enqueue/dequeue operation. The index of the device corresponds to
+the socket file in order, that means vhost device 0 is created through the first socket file,
+vhost device 1 is created through the second socket file, and so on.
+
+For more about vswitch example, please refer to the DPDK docment:
+http://doc.dpdk.org/guides/sample_app_ug/vhost.html
+
+Prerequisites
+=============
+
+Hardware
+--------
+Supportted NICs: NIC that supports VMDQ
+
+Software
+--------
+Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
+
+General set up
+--------------
+1. Compile DPDK and vhost example::
+
+ # CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=static x86_64-native-linuxapp-gcc
+ # meson configure -Dexamples=vhost x86_64-native-linuxapp-gcc
+ # ninja -C x86_64-native-linuxapp-gcc -j 110
+
+2. Get the PCI device of DUT, for example, 0000:6a:00.0 is NIC port, 0000:6a:01.0 - 0000:f6:01.0 are DSA devices::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -s
+
+ Network devices using kernel driver
+ ===================================
+ 0000:6a:00.0 'Ethernet Controller E810-C for QSFP 1592' drv=ice unused=vfio-pci
+
+ DMA devices using kernel driver
+ ===============================
+ 0000:6a:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:6f:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:74:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:79:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:e7:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:ec:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:f1:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+ 0000:f6:01.0 'Device 0b25' drv=idxd unused=vfio-pci
+
+Test case
+=========
+
+Common steps
+------------
+1. Bind 1 NIC port to vfio-pci::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <nic_pci>
+
+ For example:
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:6a:00.0
+
+2. Bind DSA devices to DPDK vfio-pci driver::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <dsa_pci>
+
+ For example, bind 2 DSA devices to vfio-pci driver:
+ <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:e7:01.0 0000:ec:01.0
+
+.. note::
+
+ One DPDK DSA device can create 8 WQ at most. Below is an example, where DPDK DSA device will create one and
+ eight WQ for DSA deivce 0000:e7:01.0 and 0000:ec:01.0. The value of “max_queues” is 1~8:
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:e7:01.0,max_queues=1 -- -i
+ <dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4 -n 4 -a 0000:ec:01.0,max_queues=8 -- -i
+
+3. Bind DSA devices to kernel idxd driver, and configure Work Queue (WQ)::
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b idxd <dsa_pci>
+ <dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q <wq_num> <dsa_idx>
+
+.. note::
+
+ Better to reset WQ when need operate DSA devices that bound to idxd drvier:
+ <dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py --reset <dsa_idx>
+ You can check it by 'ls /dev/dsa'
+ dsa_idx: Index of DSA devices, where 0<=dsa_idx<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0
+ wq_num: Number of workqueues per DSA endpoint, where 1<=wq_num<=8
+
+ For example, bind 2 DSA devices to idxd driver and configure WQ:
+
+ <dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0
+ <dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0
+ <dpdk dir># ./drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 1
+ Check WQ by 'ls /dev/dsa' and can find "wq0.0 wq1.0 wq1.1 wq1.2 wq1.3"
+
+Test Case 1: VM2VM virtio-user forwarding test when vhost async operation using DSA dpdk driver
+-----------------------------------------------------------------------------------------------
+This case tests that the imix packets can forward normally in VM2VM topology(virtio-user as front-end) when vhost async operation using DSA dpdk drvier, both split ring and packed ring have been covered.
+
+1.Bind 1 NIC port and 1 DSA device to vfio-pci.
+
+2. On host, launch dpdk-vhost by below command::
+
+ ./x86_64-native-linuxapp-gcc/examples/dpdk-vhost -l 26-28 -n 4 -a 0000:3a:00.0 -a 0000:6a:01.0,max_queues=4 \
+ -- -p 0x1 --mergeable 1 --vm2vm 1 --socket-file /root/dpdk/vhost-net0 --socket-file /root/dpdk/vhost-net1 \
+ --dmas [txd0@0000:6a:01.0-q0,rxd0@0000:6a:01.0-q1,txd1@0000:6a:01.0-q2,rxd1@0000:6a:01.0-q3] \
+ --client --total-num-mbufs 600000
+
+3. Launch virtio-user::
+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 29-30 -n 4 --no-pci --file-prefix=testpmd0 \
+ --vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/root/dpdk/vhost-net0,queues=1,server=1,mrg_rxbuf=1,in_order=0,packed_vq=1 \

+ testpmd1>set txpkts 64,256,2000,64,256,2000
+ testpmd1>start tx_first
+ testpmd1>show port stats all
+
+5. Stop dpdk-vhost side and relaunch it with below command::
+
+ ./x86_64-native-linuxapp-gcc/examples/dpdk-vhost -l 26-28 -n 4 -a 0000:3a:00.0 -a 0000:6a:01.0,max_queues=4 \
+ -- -p 0x1 --mergeable 1 --vm2vm 1 --socket-file /root/dpdk/vhost-net0 --socket-file /root/dpdk/vhost-net1 \
+ --dmas [txd0@0000:6a:01.0-q0,rxd1@0000:6a:01.0-q1] \
+ --client --total-num-mbufs 600000
+
