Subject: [PATCH] net: ehea: fix wrongly-reported supported modes

Currently EHEA reports to ethtool as supporting 10000baseT_Full and
FIBRE independent of the hardware configuration. However, these
capabilities should be reported only if the physical port and
the medium support them, which is the case where the physical port
is connected at 10Gb.
