I read this as "the virtio driver is buggy. Let's disable most of the
buggy code in one special case in which we need a driver without bugs.
In all the other cases (e.g. hardware virtio device connected over
USB-C), driver bugs are still allowed."
Can we just fix the driver without special cases?
I think we can, this is what this series tries to do:

It tries to fix without a special caring for any specific features.
Thanks
