  From: Ashish Jain <ashish.jain@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

As we can't pass SC|SP anymore can we then setup mempool cache size to some non-zero value?

#define MEMPOOL_CACHE_SIZE 256
do you think "256" will be ok?
