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

Hi All: This series tries to add the support for control virtqueue in vDPA. Control virtqueue is used by networking device for accepting various commands from the driver. It's a must to support multiqueue and other configurations. When used by vhost-vDPA bus driver for VM, the control virtqueue should be shadowed via userspace VMM (Qemu) instead of being assigned directly to Guest. This is
