The ring library is based on a lockless ring-buffer algorithm that maintains its original design for thread safety.
Moreover, it provides high performance for either multi- or single-consumer/producer enqueue/dequeue operations.
The mempool library is based on the DPDK lockless ring library and therefore is also multi-thread safe.
+rte_vhost_enqueue_burst() is also thread safe because based on lockless ring-buffer algorithm like the ring library.
