  As the SPR platform plugined NIC are all E810 series, and the E810
series NIC unsupport VMDQ, so used the testpmd to test the vhsot
aync data-path.

-====================================================================
-Vswitch sample test vhost async operation with DSA driver test plan
-====================================================================
-
-Vswitch sample can leverage DMA to accelerate vhost async data-path from dpdk 20.11. This plan test
-vhost async operation with dsa driver (kernel IDXD driver and DPDK vfio-pci driver) in vhost sample.
-For more about vswitch example, please refer to the DPDK docment:http://doc.dpdk.org/guides/sample_app_ug/vhost.html
-
-Note:
-1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1, and packed ring multi-queues not support reconnect in qemu yet.
-2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version >= 5.2.0, dut to old qemu exist reconnect issue when multi-queues test.
-3.The suite has not yet been automated.
-
-Prerequisites
-=============
-
-Software
---------
-Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz
-qemu: https://download.qemu.org/qemu-6.2.0.tar.xz
-iperf
-
-General set up
---------------
-1. Compile DPDK and vhost example::
-
-	# CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=<dpdk build dir>
-	# meson configure -Dexamples=vhost <dpdk build dir>
-	# ninja -C <dpdk build dir> -j 110
-	For example,
-	CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dexamples=all --default-library=x86_64-native-linuxapp-gcc
-	ninja -C x86_64-native-linuxapp-gcc -j 110
-
-2. Get the PCI device ID and DSA device ID of DUT, for example, 0000:4f:00.1 is PCI device ID, 0000:6a:01.0 - 0000:f6:01.0 are DSA device IDs::
-
-	<dpdk dir># ./usertools/dpdk-devbind.py -s
-
-	Network devices using kernel driver
-	===================================
-	0000:4f:00.1 '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 <DUT port pci device id>
-	For example:
-	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:4f.1
-
-2.Bind DSA devices to DPDK vfio-pci driver::
-
-	<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DSA device id>
-	For example, bind 2 DMA 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 <numDevices * 2>
-	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q <numWq> <numDevices>
-
-.. 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 <numDevices * 2>
-	You can check it by 'ls /dev/dsa'
-	numDevices: number of devices, where 0<=numDevices<=7, corresponding to 0000:6a:01.0 - 0000:f6:01.0
-	numWq: Number of workqueues per DSA endpoint, where 1<=numWq<=8
-
-	For example, bind 2 DMA devices to idxd driver and configure WQ:
-
-	<dpdk dir># ./usertools/dpdk-devbind.py -b idxd 6a:01.0 6f:01.0
-	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 1 0
-	<dpdk dir># ./<dpdk build dir>drivers/dma/idxd/dpdk_idxd_cfg.py -q 4 2
-	Check WQ by 'ls /dev/dsa' and can find "wq0.0 wq2.0 wq2.1 wq2.2 wq2.3"

-Test Case 1: PVP performance vhost async enqueue operation with dsa dpdk channel
----------------------------------------------------------------------------------
-This case uses vhost example to test performance of split and packed ring when vhost uses the asynchronous enqueue operations

-	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,packed_vq=1,server=1 \
-	-- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1
-
-4. Start pkts from virtio-user side to let vswitch know the mac addr::
-
-	testpmd>set fwd mac
-	testpmd>start tx_first
-	testpmd>stop
-	testpmd>start
-
-5. Inject pkts (packets length=64...1518) separately with dest_mac=virtio_mac_addresss (specific in above cmd with 00:11:22:33:44:10) to NIC using packet generator, record pvp (PG>nic>vswitch>virtio-user>vswitch>nic>PG) performance number can get expected.
-
-6. Quit and re-launch virtio-user with packed ring size not power of 2::

-	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0  \
-	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,packed_vq=1,server=1,queue_size=1025 -- -i --rxq=1 --txq=1 --txd=1025 --rxd=1025 --nb-cores=1
-
-7. Re-test step 4-5, record performance of different packet length.
-
-8. Quit and re-launch virtio-user with split ring::
-
-	<dpdk dir># ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 5-6 -n 4 --no-pci --file-prefix=testpmd0 \
-	--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/vhost-net,queues=1,mrg_rxbuf=0,in_order=1,server=1 -- -i --rxq=1 --txq=1 --txd=1024 --rxd=1024 --nb-cores=1
