OK. Who calls the rte_mbuf_register_platform_mempool_ops() and when?
mempool ops registration is using gcc construction scheme so it will 
be called all the time. I thought, ethdev drivers will call this API on
pci or any other bus probe() and if its in probe() then 
rte_mbuf_register_platform_mempool_ops() will be called multiple time.

What is your thought on this API usage?
