  This patch implements asynchronous dequeue data path for split ring.
A new asynchronous dequeue function is introduced. With this function,
the application can try to receive packets from the guest with offloading
copies to the DMA engine, thus saving precious CPU cycles.

note: PATCH 2/4 depends on vhost patch from Jiayu Hu
(http://patches.dpdk.org/project/dpdk/patch/1629463466-450012-1-git-send-email-jiayu.hu@intel.com/)

Wenwu Ma (3):
  examples/vhost: refactor vhost enqueue and dequeue datapaths
  examples/vhost: use a new API to query remaining ring space
  examples/vhost: support vhost async dequeue data path

Yuan Wang (1):
  vhost: support async dequeue for split ring
