This patchset introduces an unsafe API to get the number of inflight packets in DMA engine in some situations. Like vring state changes or device is destroyed. Compared with rte_vhost_async_get_inflight(), this is a lock free version. v6: * Fixed an issue of infinite loop. v5: * Rebased to the lastest branch. v4: * Added use case for API in vhost example. v3: * Fixed one typo. * Revised the doc to be more accuracy. v2: * Fixed some format issues.
