   4 Subject: [PATCH] staging: fsl-dpaa2/mac: probe phy as fixed link based on
   5  dpmac properties
   6
   7 Keep in sync the PHY type settings in DPC and Linux device tree.
   8
   9 If the dpmac is connected to a fixed link PHY based on dpc config,
  10 treat it as a fixed-link device, regardless of whether the "phy-handle"
  11 property is present in the device tree node or not.
