Actually I reverted, please fix this warning and resubmit:

drivers/net/dsa/ocelot/felix.c: In function ‘felix_phylink_mac_config’:
drivers/net/dsa/ocelot/felix.c:210:22: warning: unused variable ‘ocelot_port’ [-Wunused-variable]
  struct ocelot_port *ocelot_port = ocelot->ports[port];
                      ^~~~~~~~~~~

Thank you.
