Migrate from genphy_config_eee_advert() to genphy_c45_write_eee_adv(). It should work as before except write operation to the EEE adv registers will be done only if some EEE abilities was detected. If some driver will have a regression, related driver should provide own .get_features callback. See micrel.c:ksz9477_get_features() as example.
