Following patchset introduces dedicated group for descriptor table to reduce live migration downtime when passthrough VQ is being switched to shadow VQ. This RFC v2 is sent to incorporate the early feedback from reviewers on the uAPI and driver API part of changes, the associated driver patch set consuming ths API will come around soon along with formal submission of this series. Some initial

This patchset is pre-requisite to export and provision device config attributes and features for vdpa live migration, in a way backward and forward compatibility can be retained. The follow up work [1] will need to be built around the new feature provisioning uAPI, with which it's easier to formalize migration compatibility support at the driver level.
