Yes, phylink has its own fixed-link handling, however the
net/dsa/port.c relies on fixed_phy helpers these are not 1:1
equivalents. I assumed this migration (fixed_phy -> phylink) is not
straightforward and IMO should be handled separately. Do you recall
justification for not using phylink in this part of net/dsa/*?

Thanks,
