Async enqueue offloads large copies to DMA devices, and small copies are still performed by the CPU. However, it requires users to get enqueue completed packets by rte_vhost_poll_enqueue_completed(), even if they are completed by the CPU when rte_vhost_submit_enqueue_burst() returns. This design incurs extra overheads of tracking completed pktmbufs and function calls, thus degrading performance on small packets. This patch enhances async enqueue for small packets by enabling rte_vhost_submit_enqueue_burst() to return completed packets.
