+Subject: [PATCH] staging: fsl-dpaa2/mac: probe phy as fixed link based on
+ dpmac properties
+
+Keep in sync the PHY type settings in DPC and Linux device tree.
+
+If the dpmac is connected to a fixed link PHY based on dpc config,
+treat it as a fixed-link device, regardless of whether the "phy-handle"
+property is present in the device tree node or not.
