Check Vhost tx offload function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and\n+packed ring vhost-user/virtio-net mergeable path with CBDMA channel.\n+2. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring when\n+vhost enqueue operation with multi-CBDMA channels.\n+Note:\n+1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > v5.1.\n+2.For split virtqueue virtio-net with multi-queues server mode test, need qemu version > LTS 4.2.1,\n+DUT to old qemu exist reconnect issue when multi-queues test.\n+3.For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.\n+\n+\n+For more about dpdk-testpmd sample, please refer to the DPDK docments:\n+https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html\n+\n+For virtio-user vdev parameter, you can refer to the DPDK docments:\n+https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.\n+\n+Prerequisites\n+=============\n+\n+Topology\n+--------\n+      Test flow: Virtio-net-->Vhost-->Testpmd-->Vhost-->Virtio-net\n+\n+Hardware\n+--------\n+      Supportted NICs: ALL\n+\n+Software\n+--------\n+      Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+\n+General set up\n+--------------\n+1.

Get the PCI device ID and DMA device ID of DUT, for example, 0000:18:00.0 is PCI device ID, 0000:00:04.0, 0000:00:04.1 is DMA device ID::\n+\n+      <dpdk dir># ./usertools/dpdk-devbind.py -s\n+\n+      Network devices using kernel driver\n+      ===================================\n+      0000:18:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci\n+\n+      DMA devices using kernel driver\n+      ===============================\n+      0000:00:04.0 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci\n+      0000:00:04.1 'Sky Lake-E CBDMA Registers 2021' drv=ioatdma unused=vfio-pci\n+\n+Test case\n+=========\n+\n+Common steps\n+------------\n+1. Bind 2 CBDMA channels to vfio-pci::\n+\n+      <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port DMA device id>\n+\n+      For example, Bind 1 NIC port and 2 CBDMA channels::\n+      <dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci 0000:00:04.0,0000:00:04.1\n+\n+Test Case 1: VM2VM split ring vhost-user/virtio-net CBDMA enable test with tcp traffic\n+--------------------------------------------------------------------------------------\n+This case uses testpmd and QEMU and iperf to test split ring and CBDMA enable to get throughput between 2 VMs.\n+\n+1.
