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. Thanks, -Siwei [1] [PATCH v3 0/4] vDPA:

Live migration of vdpa would typically require re-instate vdpa device with an idential set of configs on the destination node, same way as how source node created the device in the first place. In order to allow live migration orchestration software to export the initial set of vdpa attributes with which the device was created, it will be useful if the vdpa tool can report the config on demand
