This would allow all current applications to work without any ABI breakage and only require adding a new API call for anyone that wants the name. The rte_pktmbuf_pool_create() routine could assign a default name or some incrementing style name as the default. e.g. ‘pktmbuf_%d’ with a static incrementing variable or whatever you like.
