Thanks for the review Olivier.

Just to make sure the correct one is reviewed.

1) v7 had similar issue mentioned
http://patches.dpdk.org/patch/56585/

2) v11 addressed the review comments and you have given the Acked-by
for mempool change
http://patches.dpdk.org/patch/61559/

My thought process in the TB meeting was, since
rte_mempool_populate_from_pg_sz_chunks() reviwed
replace rte_pktmbuf_pool_create's  rte_mempool_populate_default() with
rte_mempool_populate_from_pg_sz_chunks()
in IOVA == VA case to avoid a new KNI mempool_create API.

OK.

For KNI use case, we would need _physically_ contiguous to make sure
that using, get_user_pages_remote() we get  physically contiguous memory map,
so that both KNI kernel thread and KNI kernel context and DPDK userspace can
use the same memory in different contexts.

If the above is the requirement, Does this logic need to be in slow
path or fast path?

OK.
