Please split this into two patches. One patch for the PHY you are interested in, and a second patch to remove phy_set_max_speed() and fix up that PHY. Also, i would prefer you do the normal feature discovery, calling genphy_read_abilities() and/or genphy_c45_pma_read_abilities() and then fixup the results by removing the modes which should not be there. Take a look at bcm84881_get_features() as an example. Andrew
