[dpdk-dev] [PATCH RFC 0/1] vhost-add-DMADEV-support-for-async-datapath

[Sunil Pai G <sunil.pai.g@intel.com>]

Note to the reader:
-------------------
The intent of this patch is to explore possible different approaches
of async implementations.
Please consider this patch for discussions only and not for
merge/upstream.

This patch simplifies the vhost async datapath usability by
utilizing the generic DMADEV API's to perform packet copy.

Previously, it was required by the application to implement its
own DMA enabling logic making it difficult to adopt this feature.
Having a common implementation in vhost library allows
for easier adoption.

The usability of async datapath is enhanced by extending the
API's to include a DMADEV ID to be passed by the application.
This provides flexibility to applications to decide which DMADEV to be used.
