At least on the i350 there is an annoying behavior that is maybe also
present on 82580 devices, but was probably not noticed yet as MAS is not
widely used.
If no cable is connected on both fiber/copper ports the media auto sense
code will constantly swap between them as part of the watchdog task and
produce many unnecessary kernel log messages.
The swap code responsible for this behavior (switching to fiber) should
not be executed if the current media type is copper and there is no signal
detected on the fiber port. In this case we can safely wait until the
AUTOSENSE_EN bit is cleared.
