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.
