description: >
    Describe an MCTP endpoint. It is an MCTP communication terminus. An MCTP
    endpoint is a terminus or origin of MCTP packets or messages. The combined
    functionality within a physical device that communicates using the MCTP
    transport protocol and handles MCTP control commands. This includes
    MCTP-capable management controllers and managed devices.

properties:
    - name: NetworkId
      type: size
      description: >
          A locally defined identifier to distinguish each independent MCTP
          network within a platform. The network IDs are used by the MCTP stack
          to index separate MCTP Networks. This along with EID is used by upper
          layer protocols to address the destination endpoint.

    - name: EID
      type: size
      description: >
          The logical address used to route MCTP messages to a specific MCTP
          endpoint. A numeric handle (logical address) that uniquely identifies
          a particular MCTP endpoint within a system for MCTP communication and
          message routing purposes. Endpoint IDs are unique among MCTP
          endpoints that comprise an MCTP communication network within a
          system. MCTP EIDs are only unique within a particular MCTP network.
          That is, they can be duplicated or overlap from one MCTP network to
          the next. This is also referred to as "endpoint ID" and abbreviated
          as "EID".

    - name: SupportedMessageTypes
      type: array[byte]
      description: >
          List of MCTP message types supported by the MCTP endpoint. MCTP
          message type is an enumeration that identifies the type of the
          communication payload in an MCTP message. The well defined message
          types are MCTP Control(0x00), PLDM(0x01), NC-SI over MCTP(0x02),
          Ethernet over MCTP(0x03), NVM Express Management Messages over
          MCTP(0x04) and SPDM over MCTP(0x05). There are ranges for vendor
          defined message types. All the message types are specified in the
          DSP0239 specification. A device that supports a given message type
          may not support that message type equally across all buses that
          connect to the device.
