Kaike Wan c2be3865a1 IB/hfi1: Calculate flow weight based on QP MTU for TID RDMA ... For a TID RDMA WRITE request, a QP on the responder side could be put into a queue when a hardware flow is not available. A RNR NAK will be returned to the requester with a RNR timeout value based on the position of the QP in the queue. The tid_rdma_flow_wt variable is used to calculate the timeout value and is determined by using a MTU of 4096 at the module loading time. This could reduce the timeout value by half from the desired value, leading to excessive RNR retries. This patch fixes the issue by calculating the flow weight with the real MTU assigned to the QP.
