Good idea.

However, I prefer it to be implemented in the ring lib as one more ring type. That would also give us a lot of the infrastructure (management functions, documentation and tests) for free.

The ring lib already has performance-optimized APIs for single-consumer and single-producer use, rte_ring_sc_dequeue_bulk() and rte_ring_sp_enqueue_burst(). Similar performance-optimized APIs for single-thread use could be added: rte_ring_st_dequeue_bulk() and rte_ring_st_enqueue_burst().

Regardless if added to the ring lib or as a separate lib, "reverse" APIs (for single-thread use only) and zero-copy APIs can be added at any time later.
