The current get_phy_flags() is only processed when we connect to a PHY via a designed phy-handle property via phylink_of_phy_connect(), but if we fallback on the internal MDIO bus created by a switch and take the dsa_slave_phy_connect() path then we would not be processing that flag and using it at PHY connection time.
