Are you sure about this - we already have a bunch of "ethernet" modes
that are more specific, like PHY_MODE_SGMII, PHY_MODE_2500SGMII and
PHY_MODE_10GKR which require PHYs to be configured differently. Having
a very generic "ethernet" mode brings up questions about when it should
be used vs the more specific modes.

(I've already mentioned that the SGMII modes are mis-named, since
they also apply to 1000base-X and 2500base-X - the only difference
is how one 16-bit word in the data stream is used which has no effect
on the PHY.)
