Still, I am not sure, in current kernels and currently available Ethernet DPDK PMDs about the answer to my queries (I don't think this mail thread gives info about it), like about what are the benefits of providing DPDK VFs, is it mandatory in some use cases, and are there any advantage for using a DPDK PF/DPDK VF combination over using Kernel VF?
