  label:
    description:
      Describes the label associated with this port, which will become
      the netdev name

    description:
      Should be a list of phandles to other switch's DSA port. This
      port is used as the outgoing port towards the phandle ports. The
      full routing information must be given, not just the one hop
      routes to neighbouring switches

  ethernet:
    description:
      Should be a phandle to a valid Ethernet device node.  This host
      device is what the switch port is connected to

  dsa-tag-protocol:
    description:
      Instead of the default, the switch will use this tag protocol if
      possible. Useful when a device supports multiple protocols and
      the default is incompatible with the Ethernet device.
