This commit implements a new function ifcvf_get_driver_feature() which read driver_features from virtio registers. To be less ambiguous, ifcvf_set_features() is renamed to ifcvf_set_driver_features(), and ifcvf_get_features() is renamed to ifcvf_get_dev_features() which returns the provisioned vDPA device features.

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.
