   4 Subject: [PATCH] net: dsa: felix: Don't error out on disabled ports with no
   5  phy-mode
   6
   7 The felix_parse_ports_node function was tested only on device trees
   8 where all ports were enabled. Fix this check so that the driver
   9 continues to probe only with the ports where status is not "disabled",
  10 as expected.
