This description covers details we can see in the patch itself. Can you please rather describe the motivation and any related considerations, e.g. answer: * What devices will you be managing via MCTP? * How do they affect the function of the platform? - Alternatively, how does _not_ having the MCTP capability to manage them impact the function of the platform? The general advice provided here might be helpful: https://docs.kernel.org/process/submitting-patches.html#describe-your-chang= es Andrew
