xdp: generic XDP handling of xdp_rxq_info
Hook points for xdp_rxq_info: * reg : netif_alloc_rx_queues * unreg: netif_free_rx_queues The net_device have some members (num_rx_queues + real_num_rx_queues) and data-area (dev->_rx with struct netdev_rx_queue's) that were primarily used for exporting information about RPS (CONFIG_RPS) queues to sysfs (CONFIG_SYSFS). For generic XDP extend struct netdev_rx_queue with the xdp_rxq_info, and remove some of the CONFIG_SYSFS ifdefs.
