Kaike Wan ce8e8087cf IB/hfi1: TID RDMA WRITE should not return IB_WC_RNR_RETRY_EXC_ERR ... Normal RDMA WRITE request never returns IB_WC_RNR_RETRY_EXC_ERR to ULPs because it does not need post receive buffer on the responder side. Consequently, as an enhancement to normal RDMA WRITE request inside the hfi1 driver, TID RDMA WRITE request should not return such an error status to ULPs, although it does receive RNR NAKs from the responder when TID resources are not available. This behavior is violated when qp->s_rnr_retry_cnt is set in current hfi1 implementation. This patch enforces these semantics by avoiding any reaction to the updates of the RNR QP attributes.
