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