Use the newly introduced phy_caps_lookup to get these modes instead of phy_lookup_settings(). This has the side effect that the matched settings and configured linkmodes may now contain several linkmodes (the intersection of supported linkmodes from the phylink settings and the linkmodes that match speed/duplex) instead of the one from phy_lookup_settings().
