 - Patch #14-#18: memory copy optimization for the case using loopback.

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.
