DPDK PF working with DPDK VF is not new scenario at all. It was already sup= ported. 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 obje= ct that. Thanks Jingjing
