net: loopback driver cleanup
loopback driver uses dev->ml_priv to store its percpu stats pointer. It uses ugly casts "(void __percpu __force *)" to shut up sparse complains. Define an union to better document we use ml_priv in loopback driver and define a lstats field with appropriate types. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
