Re: [edk2-devel] SPDM Transports

["Yao, Jiewen" <jiewen.yao@intel.com>]

Hi Tim/Alistair
Is there any detailed proposal, as such we can have a discussion?

I am not sure what is the plan for the driver model version MCTP. If it is something mature, we can definitely discuss it.

Thank you
Yao, Jiewen
