DPDK PF working with DPDK VF is not new scenario at all. It was already supported.
This patchset just adds more features from my view.

Even if DPDK PF supports Kernel VF, it is a way to make VF and PF's driver low coupling.
User can define their scenario flexibly. I don't what is the reason to object that.
