I don't see any problem with reporting full-duplex all the time if you
don't support any half-duplex link modes.  But we don't yet have
consistency between drivers in speed/duplex reporting while the link is
down, so I won't insist that that is the right thing to do.

However you should use DUPLEX_UNKNOWN rather than -1.
