Please, it has to be proven that DPDK provides the same interface that the kernel. It seems insane to duplicate kernel's PF into the DPDK without a strong guarantee that it is a strict same behaviour. For instance, - what will happen when the DPDK's PF will have a new feature which is not into the kernel? - what will happen when the Kernel's PF will have a feature with different capabilities that the kernel? Please, make it clear before. Currently, for me it is a nack of this serie. Thank you, Vincent
