This is IBTA behavior. 5.2.11 IMMEDIATE DATA EXTENDED TRANSPORT HEADER (ImmDt) - 4 BYTES "Immediate Data (ImmDt) contains data that is placed in the receive Completion Queue Element (CQE). The ImmDt is only allowed in SEND or RDMA WRITE packets with Immediate Data." If I understand the spec, you shouldn't set imm_data in SQ. Thanks
