[PATCH v3 0/4] vDPA: initial config export via "vdpa dev show"
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
