This series implements features provisioning for vduse devices. This allows
the device provisioner to clear the features exposed by the userland device, so
the driver never see them. The intended use case is to provision more than one
different device with the same feature set, allowing live migration between
them.

The device addition validates the provisioned features to be a subset of the
parent features, as the rest of the backends.

Eugenio Pérez (2):
vduse: support feature provisioning
vduse: allow to specify device-specific features if it's multiclass
