ethtool: Report link-down while interface is down
While an interface is down, many implementations of ethtool_ops::get_link, including the default, ethtool_op_get_link(), will report the last link state seen while the interface was up. In general the current physical link state is not available if the interface is down. Define ETHTOOL_GLINK to reflect whether the interface *and* any physical port have a working link, and consistently return 0 when the interface is down.
