    description:
      Use the NC-SI stack instead of an MDIO PHY. Currently assumes
      rmii (100bT) but kept as a separate property in case NC-SI grows support
      for a gigabit link.

    description:
      Used to disable HW checksum support. Here for backward
      compatibility as the driver now should have correct defaults based on
      the SoC.
