+Subject: [PATCH] staging: octeon: sgmii to honor disabled dt node status
+
+With this patch, sgmii interface device tree node could be disabled and
+that disabled interface will not be unnecessarily initialized.
+
+It solves the problem with Octeon boards that have 8 sgmii or more ports
+initialized but have nothing connected to them.
+
+Tested-by: Johannes Kimmel <fff@bareminimum.eu>
