If this is what is necessary, you're taking some of the configuration
out of phylink's control, effectively making port 6 a fixed-interface
mode port. In that case, there should only ever be one interface
mode set in port 6's supported_interface mask, so that phylink knows
that no other interface modes can be selected for that port.
