Subject: [edk2-devel] [PATCH edk2-platforms v2 01/15] ManageabilityPkg: Add definition for the MCTP KCS TRAILER structure
Date: Fri, 20 Oct 2023 15:52:48 +0300	[thread overview]
Message-ID: <20231020125302.1459-2-aladyshev22@gmail.com> (raw)
In-Reply-To: <20231020125302.1459-1-aladyshev22@gmail.com>

Currently there is only a definition for the MCTP KCS HEADER structure.
Add definition for the MCTP KCS TRAILER structure as well.
