[dpdk-dev] [PATCH] examples/ip_reassembly: use pktmbuf to create pool

From: Ashish Jain <ashish.jain at nxp.com>

Use of rte_mempool_create() with the helper provided in
librte_mbuf: rte_pktmbuf_pool_create().
This is the preferred way to create a mbuf pool else
it may not work on implementation using the HW buffer pool
