This can lead to some strange deductions in certain versions of ethtool. When the device is up and the link is down, the driver reports SPEED_INVALID and DUPLEX_INVALID for these fields. This patch makes the presentation consistent by returning SPEED_INVALID and DUPLEX_INVALID when the device has not been brought up as well.
