It's the kernel internal API, so there's no strict requirement for this. We
will export a version value for userspace for compatibility.
Given it's tied to virtio we probably want kernel+userspace
feature bits?
Yes, then I think we could probably have a version field inside e.g
device_ops structure. Then it could be fetched from both kernel and
userspace driver.
Thanks
my point was feature bits not a version number.
Something like backend_feature that current vhost_net did?
Thanks
