I think, exposing the internal_config may not be a good idea. We may
need "plat_mbuf_pool_ops_name" value for multi process case too.
Considering the above points, How about adding it in
struct rte_config and then expose too rte_eal_get_configuration()
On the downside, it would be an ABI change.

Yes! I was also not sure about exposing internal_config.

rte_config is also a good option. If  we add these options in the end, 
it should not break ABI?

I think, it does break the ABI.

What about a new API in librte_mbuf as suggested as a reply to the cover
letter?
