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
large copies to the DMA engine, thus saving precious CPU cycles.

- Allocate and
Previously, by judging the flag, we call different enqueue/dequeue
functions in data path.
Now, we use an ops that was initialized when Vhost was created,
so that we can call ops directly in Vhost data path without any more
flag judgment.

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 large copies to the async channel, thus saving precious CPU
cycles.
This patch is to add vhost async dequeue data-path in vhost sample.
vswitch can leverage IOAT to accelerate vhost async dequeue data-path.

Added unit test for ethdev APIs, this unit test 'ethdev_api_autotest'
can run without physical device. If there are physical devices probed,
they will be ignored by the unit test.
A few issues fixed or some clarification added in the ehtdev library
with in this unit test patch.
