If we have a MAC driver which does not implement the ethtool set_eee()
and get_eee() ops, and a dev->phydev with the SmartEEE flag set, we
could have net/ethtool/eee.c call direct into phylib.

As for PTP and EEE, maybe we want the core PTP code to try calling
get_eee() and at minimum issue a warning if it is enabled, if it
thinks MAC PTP is being used?
