One or more passthrough PCI VF devices are ubiquitous for virtual
machines usage using generic kernel framework such as vfio [1].
Mentioning a specific subsystem in a specific OS may mislead the
user to think it can only work in that setup. Let's not do that,
virtio is not only used for Linux and VFIO.
This is just one example on how these commands are useful.
It can be useful in more ways too in more OSes too.
I will drop from the patch commit log and keep as information purpose in
cover letter.
Would that work for you?

I donât have any strong opinion to keep it or remove it as most stakeholders
has the clear view of requirements now.
Let me know.
So some people use VFs with VFIO. Hence the module name.  This sentence by
itself seems to have zero value for the spec. Just drop it.
Ok. Will drop.
So why not build your admin vq live migration on our config space solution,
get out of the troubles, to make your life easier?

Actually you don't see any technical problems in our config space proposal, right?
