+Subject: [PATCH] staging: octeon: add net-labels support
+
+With this patch, device name can be set within dts file
+in the same way as dsa port can.
+
+Add label to pip interface node to use this feature:
+label = "lan0";

+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.
