Web18 jan. 2024 · As mentioned above, MCTP packets have two header fields related to tags: A three-bit tag value field. A one-bit tag owner field, also known as TO. These provide a basic method of both correlating packets of a fragmented message, and correlating request messages with their replies. The general semantics of these fields are: Webmctp i2c: Fix hard head TX bounds length check: Matt Johnston: 1-2 / +3: We should be testing the length before fitting into the u8 byte_count.
