Version 5: * Fixed incorrect handling of rtnl_lock. Version 4: * 'xdp_umem_clear_dev' exposed to be used while unregistering. * Added XDP socket state to track if resources already unbinded. * Splitted in two fixes. Version 3: * Declaration lines ordered from longest to shortest. * Checking of event type moved to the top to avoid unnecessary locking. Version 2: * Completely re-implemented using netdev event handler.
