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

11      description: >
12          A locally defined identifier to distinguish each independent MCTP
13          network within a platform. The network IDs are used by the MCTP stack
14          to index separate MCTP Networks. This along with EID is used by upper
15          layer protocols to address the destination endpoint.

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

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