      description
        "This typedef specifies a Stream ID, a unique identifier of the
      Stream's configuration, used by protocols in the network to associate
      the user's Stream with TSN resources.
      
      The Stream ID is a string that represents two fields:
      
      MAC Address:
      
      A 48-bit IEEE 802 MAC address associated with the Talker sourcing the
      Stream to the bridged network. The entire range of MAC addresses are
      acceptable.
      
      NOTE 1The MAC address component of the StreamID can, but does not
      necessarily, have the same value as the source_address parameter of
      any frame in the actual data Stream. For example, the Stream ID can be
      assigned by a TSN CUC (see 46.1.3.3 of IEEE Std 802.1Q-2021), using a
      pool of MAC addresses that the TSN CUC maintains.
      
      NOTE 2If the MAC addresses used to construct Stream IDs are not unique
      within the network, duplicate Stream IDs can be generated, with
      unpredictable results.
      
      Unique ID:
      
      A 16-bit unique ID that is used to distinguish between multiple
      Streams within the station identified by MAC Address.
      
      The string specifies eight octets, with each octet represented as two
      hexadecimal characters. The first six octets specify the MAC Address,
      using the canonical format of IEEE Std 802, with a dash separating
      each octet. The last two octets specify the Unique ID, with the
      high-order octet, a dash, and then the low-order octet. The MAC
      Address and Unique ID are separated by colon.
      
      stream-id-type is intended for use by other modules as the type for a
      key to a list of Stream configurations (using group-talker and
      group-listener) and a list of Stream status (using group-status-stream
      and group-status-talker-listener).";
