Are these "rc_compare_swap_mr, rc_fetch_add_mr, ver_rc_compare_swap and ver_rc_fetch_add" reporting an invalid op code? Those are unsupported in i40iw. qperf I think uses write with immediate which is also unsupported in i40iw and could explain the rdma_write_* fails. For performance benchmarking on x722, we are typically using perftests (ib_* tests) Shiraz
