[dpdk-dev] [PATCH v6 11/25] lib/librte_vhost: rte_vhost_en/dequeue_burst API

[Huawei Xie <huawei.xie@intel.com>]

rte_vhost_enqueue_burst will call virtio_dev_rx and virtio_dev_merge_rx respectively depending on
whether merge-able feature is negotiated or not in the vhost device.
virtio_dev_merge_tx is renamed to rte_vhost_dequeue_burst.
