I notice that no other app or example is using the create_by_ops except
pdump/pcapng/dumpcap.
~/DPDK/main/examples $ git grep rte_pktmbuf_pool_create_by_ops
~/DPDK/main/app $ git grep rte_pktmbuf_pool_create_by_ops
dumpcap/main.c: mp = rte_pktmbuf_pool_create_by_ops(pool_name, num_mbufs,
pdump/main.c: mbuf_pool =
rte_pktmbuf_pool_create_by_ops(mempool_name,
test/test_pcapng.c: mp = rte_pktmbuf_pool_create_by_ops("pcapng_test_pool",
IOV_MAX + NUM_PACKETS,
