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
