Port Representors provide a logical presentation in DPDK of VF (virtual function) ports for the purposes of control and monitoring. Each port representor device represents a single VF and is associated with it's parent physical function (PF) PMD which provides the back-end hooks for the representor device ops and defines the control domain to which that port belongs. This allows to use existing DPDK APIs to monitor and control the port without the need to create and maintain VF specific APIs.
This patch adds to the i40e PMD the functions required to enable port representor functionality.
