This is in the library, not sure if libraries should include the header file for
the drivers, can you please explain why this change is needed?

I was hoping "rte_ethdev_core.h" can be removed completely by distributing its
content to "ethdev_private.h", "rte_ethdev_driver.h" and perhaps even to
"rte_ethdev.h".

Can you please explain what prevents removing "rte_ethdev_core.h"?
