ethernet-controller.yaml says:

  phy-connection-type:
    description:
      Specifies interface type between the Ethernet device and a physical
      layer (PHY) device.
    enum:
      # There is not a standard bus between the MAC and the PHY,
      # something proprietary is being used to embed the PHY in the
      # MAC.
      - internal
      - mii
      - gmii
  ...

  phy-mode:
    $ref: "#/properties/phy-connection-type"


so phy-mode and phy-connection-type are the same thing.

sff,sfp.yaml says:

  maximum-power-milliwatt:
    minimum: 1000
    default: 1000
    description:
      Maximum module power consumption Specifies the maximum power consumption
      allowable by a module in the slot, in milli-Watts. Presently, modules can
      be up to 1W, 1.5W or 2W.

I've no idea what will happen when the SFP core sees 3000. Is the
comment out of date?
