[PATCH v1 0/2] vhost: add unsafe API to get DMA inflight packets

[xuan.ding at intel.com]

From: Xuan Ding <xuan.ding at intel.com>

This patchset introduces an unsafe API to get the number of inflight
packets in DMA engine. It should be only used within the vhost ops
which already holds the lock. Like vring state changes or device is
destroyed. Compared with rte_vhost_async_get_inflight(), this is a
lock free version.

RFC v1->v1:
* refine the doc and commit log
