Description
===========
-Vhost asynchronous data path leverages DMA devices to offload memory copies from the CPU and it is implemented in an asynchronous way.
-In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA
-channels and one DMA channel can be shared by multiple vrings at the same time.From DPDK22.07, Vhost enqueue and dequeue operation with
-CBDMA channels is supported in both split and packed ring.
+CBDMA is a kind of DMA engine, Vhost asynchronous data path leverages DMA devices
+to offload memory copies from the CPU and it is implemented in an asynchronous way.
+As a result, large packet copy can be accelerated by the DMA engine, and vhost can
+free CPU cycles for higher level functions. In addition, vhost supports M:N mapping
+between vrings and DMA virtual channels. Specifically, one vring can use multiple
+different DMA channels and one DMA channel can be shared by multiple vrings at the
+same time. From DPDK22.07, Vhost enqueue and dequeue operation with CBDMA channels
+is supported in both split and packed ring.
+
This document provides the test plan for testing the following features when Vhost-user using asynchronous data path with
CBDMA in VM2VM virtio-net topology.
-1. Check Vhost tx offload（TSO） function by verifing the TSO/cksum in the TCP/IP stack with vm2vm split ring and packed ring

2.Check the payload of large packet (larger than 1MB) is valid after forwarding packets with vm2vm split ring
and packed ring vhost-user/virtio-net mergeable and non-mergeable path.
-3. Multi-queues number dynamic change in vm2vm vhost-user/virtio-net with split ring and packed ring.

+
+ 1.For packed virtqueue virtio-net test, need qemu version > 4.2.0 and VM kernel version > 5.1, and packed ring multi-queues not support reconnect in qemu yet.
+ 2.For split virtqueue virtio-net with multi-queues server mode test, better to use qemu version >= 5.2.0, dut to qemu(v4.2.0~v5.1.0) exist split ring multi-queues reconnection issue.
+ 3.When DMA devices are bound to vfio driver, VA mode is the default and recommended. For PA mode, page by page mapping may
+ exceed IOMMU's max capability, better to use 1G guest hugepage.
+ 4.DPDK local patch that about vhost pmd is needed when testing Vhost asynchronous data path with testpmd. In this patch,
+ we enable asynchronous data path for vhostpmd. Asynchronous data path is enabled per tx/rx queue, and users need to specify
+ the DMA device used by the tx/rx queue. Each tx/rx queue only supports to use one DMA device (This is limited by the
+ implementation of vhostpmd), but one DMA device can be shared among multiple tx/rx queues of different vhost PMD ports.
