Kaike Wan f4d46119f2 IB/hfi1: Drop all TID RDMA READ RESP packets after r_next_psn ... When a TID sequence error occurs while receiving TID RDMA READ RESP packets, all packets after flow->flow_state.r_next_psn should be dropped, including those response packets for subsequent segments. The current implementation will drop the subsequent response packets for the segment to complete next, but may accept packets for subsequent segments and therefore mistakenly advance the r_next_psn fields for the corresponding software flows. This may result in failures to complete subsequent segments after the current segment is completed. The fix is to only use the flow pointed by req->clear_tail for checking KDETH PSN instead of finding a flow from the request's flow array.
