I need to update mv88e6xxx_mac_link_up to not force the link when mode == MLO_AN_INBAND. I also have a problem with mv88e6xxx_serdes_pcs_get_state expecting mv88e6xxx_serdes_get_lane() to return a lane number. Implementing mv88e6xxx_serdes_get_lane() for the mv88e6097 causes a lot of other code paths to trigger which didn't before. I think I'm close to getting something sensible working for my hardware but I'm off on leave for a week so I just wanted to get this out before I go.
