For\nphysical port representors the current logic aims to create a\nrepresentor for each physical port present on the hardware.\n\nA eth_dev is created for each phyport and VF, and flower firmware\nrequires a MAC repr cmsg to be transmitted to firmware with\ninfo about the number of physical ports configured.\n\nReify messages are sent to hardware for each phyport representor.\nA rte_ring is also created per representor so that traffic can be\npushed and pulled to this interface.\n\nTo up and down the real device represented by a flower representor port\na port mod message is used to convey that info to the firmware. This\nmessage will be used in the dev_ops callbacks of flower representors.\n\nEach cmsg generated by the driver is prepended with a cmsg header.\nThis commit also adds the logic to fill in the header of cmsgs.\n\nThis commit also adds the Rx and Tx path for flower representors. For\nRx packets are dequeued from the representor ring and passed to the\neth_dev. For Tx the first queue of the PF vNIC is used. Metadata about\nthe representor is added before the packet is sent down to firmware.\n\nSigned-off-by: Chaoyong He <chaoyong.he@corigine.com>\nReviewed-by: Niklas Söderlund
