dsa-1dwq is the mdev type.
there's no dsa-2dwq yet. and I think no dsa-2dwq should be provided in
future according to our discussion.
GVT currently does not support aggregator also.
how to add the the aggregator attribute is currently uder discussion,
and up to now it is recommended to be a vendor specific attributes.
