Add a front end VDPA driver that registers in the VDPA bus and provides networking to a guest. The VDPA driver creates the necessary resources on the VF it is driving such that data path will be offloaded. Notifications are being communicated through the driver. Currently, only VFs are supported. In subsequent patches we will have devlink support to control which VF is used for VDPA and which function is used for regular networking.
