I don't want to see this value increase, either this is ABI compatible
with i40iw or it is not and should be a new driver_id.
This should have a small diff against include/uapi/rdma/i40iw-abi.h
that is obviously compatible

For instance these are almost the same, why put qp_caps in the middle?
Add it to the end so the whole thing is properly compatible with a
single structure.
