Your cover letter is very well helpful, thanks a lot for that. I really like the way you grouped the patches. Just a thought: If it takes too long to get this large patchset reviewed, you could split it up into smaller sets and get them upstream one after the other. I think it is especially valuable to more crisply define the interface between SMC-D and the smc-d devices, given that virtio-ism may soon be a third kind of smcd device.
