[PATCH RFC v2 0/3] vdpa: dedicated descriptor table group
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.
