The UDP source port number in RoCE v2 is used to create entropy for network routers (ECMP), load balancers and 802.3ad link aggregation switching that are not aware of RoCE IB headers. Considering that the IB core has achieved a new interface to get a hashed value of it, the fixed value of it in QPC and UD WQE in hns driver could be fixed and the port number is to be set dynamically now. For QPC of RC, the value could be hashed from flow_lable if the user pass it in or from remote qpn and local qpn. For WQE of UD, it is set according to fl or as a random value.
