Add infrastructure for ethtool netlink notifications. There is only one multicast group "monitor" which is used to notify userspace about changes and actions performed. Notification messages (types using suffix _NTF) share the format with replies to GET requests. Notifications are supposed to be broadcasted on every configuration change, whether it is done using the netlink interface or ioctl one. Netlink SET requests only trigger a notification if some data is actually changed. To trigger an ethtool notification, both ethtool netlink and external code use ethtool_notify() helper. This helper requires RTNL to be held and may sleep. Handlers sending messages for specific notification message types are registered in ethnl_notify_handlers array. As notifications can be triggered from other code, ethnl_ok flag is used to prevent an attempt to send notification before genetlink family is registered.
