[PATCH v4] net/vhost: support asynchronous data path

2022-09-29 Thread Yuan Wang
Vhost asynchronous data-path offloads packet copy from the CPU to the DMA engine. As a result, large packet copy can be accelerated by the DMA engine, and vhost can free CPU cycles for higher level functions. In this patch, we enable asynchronous data-path for vhostpmd. Asynchronous data path is e
