This patch set makes vhost-vswitch be able to use vhost async APIs for enqueue operations. Demonstrated how the application leverage IOAT DMA channel with vhost async APIs.
We introduce two parameters to enable DMA acceleration for Tx operations of queues: -async_vhost_driver Async vhost-user net driver will be used when this option is given. It is disabled by default. -dmas This parameter is used to specify the assigned DMA device of a vhost device.
