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

+ 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.
+
+ Two PMD parameters are added:
+ - dmas: specify the used DMA device for a tx/rx queue.(Default: no queues enable asynchronous data path)
+ - dma-ring-size: DMA ring size.(Default: 4096).
