net: sysfs: ethtool_ops can be NULL
commit d519e17e2d01a0ee9abe083019532061b4438065 (net: export device speed and duplex via sysfs) made the wrong assumption that netdev->ethtool_ops was always set. This makes possible to crash kernel and let rtnl in locked state. modprobe dummy ip link set dummy0 up (udev runs and crash) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.
