The SM must be configured with QoS.  You'll need to look in the opensm QoS

IB specifies qos using the service ID and qos_class fields in the PR query.
This is done during 'route resolution'.  See cma_query_ib_route().

>Can we set it in transport independent way?

See rdma_set_service_type().  This call is intended to be generic.
