If we are going to talk about API surface area lets talk about ethdev then :-)

Ok, lets create a new librte_gro, but I am not convinced it is reasonable. Maybe a better generic name is needed if we are going to add GSO to the library too. So a new name for the lib is better then librte_gro, unless you are going to create another library for GSO.

I still think the design needs to be integrated in as a real offload as I stated before and that is not something I am willing let drop.
