Split ring and packed ring vm2vm test when vhost enqueue operation with multi-CBDMA channels.\n+2. payload check\n+3. iova=pa mode (When DMA devices are bound to vfio driver, VA mode is the default and recommended.\n+For PA mode, page by page mapping may exceed IOMMU's max capability, better to use 1G guest hugepage.)\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-user-->Vhost-user-->Testpmd-->Vhost-user-->Virtio-user\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.
