I'll add a +1 in interest for MCTP.
Performance would be better if this is moved to the kernel, but I'm a bit
curious about any other pros and cons of working in userspace.
One of our most immediate use cases for MCTP would be in a UEFI BIOS before
a Redfish client can be bootstrapped. Would things be more portable for
BIOS vendors if this is done in userspace. I genuinely don't know enough
about that area to know which is more flexible.
