I haven't looked too closely, but maybe you can add a new mdiobus_scan function for 10G that attempts get_phy_device() with is_c45 set to true and if nothing is found falls back to get_phy_device() with is_c45 set to false. I don't know what would happen if you have a non-c45 phy attached, but it's worth a shot to try it and see for each situation. Thanks, Tom > > Well, DT can be used with x86. I think Edison did that.
