This method is used to properly allow kernel callers of the IPv4 route management ioctls. The exsting ip_tunnel_ioctl helper is renamed to ip_tunnel_ctl to better reflect that it doesn't directly implement ioctls touching user memory, and is used for the guts of ndo_tunnel_ctl implementations. A new ip_tunnel_ioctl helper is added that can be wired up directly to the ndo_do_ioctl method and takes care of the copy to and from userspace.
