It is good to explain things in the release notes, but not sufficient. We must explain the DPDK position about PF/VF in the design doc: http://dpdk.org/doc/guides/contributing/design.html It is important to explain that the primary goal of DPDK is to provide a userland dataplane. Managing VF from a PF driver is a control plane feature and we generally rely on the kernel for that. So we continue adding some PF features in DPDK as experimental functions but they must be implemented in the kernel with the same messaging interface.
