Hi, this series adds a flower app to the NFP driver. It initialises four types of netdevs:
* PF netdev - lower-device for communication of packets to device * PF representor netdev * VF representor netdevs * Phys port representor netdevs The PF netdev acts as a lower-device which sends and receives packets to and from the firmware. The representors act as upper-devices. For TX representors attach a metadata dst to the skb which is used by the PF netdev to prepend metadata to the packet before forwarding the firmware. On RX the PF netdev looks up the representor based on the prepended metadata recieved from the firmware and forwards the skb to the representor after removing the metadata. Control queues are used to send and receive control messages which are used to communicate configuration information with the firmware. These are in separate vNIC to the queues belonging to the PF netdev. The control queues are not exposed to use-space via a netdev or any other means. As the name implies this app is targeted at providing offload of TC flower. That will be added by follow-up work. This patchset focuses on adding phys port and VF representor netdevs to which flower classifiers may be attached.
