<div>Hello,</div><div><br></div><div>I have been looking at doing some low level work with the OFED library 1.1 in terms of figuring out how many bytes have been sent by an IB application. </div><div>I came across the byte_cnt field inside the MTHCA_CQE structure and was wondering if this indicates the number of bytes that are sent/received?</div>
<div><br></div><div>From the cq.c file in the libmthca/src folder it looks like the value is copied from the CQE structure to the WQE struct in the case of RDMA reads but not RDMA writes. Is there a reason for this? Has this been implemented in newer versions of OFED? Im currently working with OFED-1.1.</div>
<div><br></div><div>When using the performance tests inside OFED the value of the byte_cnt field is set to the buffer size in case of RDMA read but to a very large value >> buffer size in case of RDMA Write.</div><div>
<br></div><div>Im using a Mellanox HCA MT25208 Infinihost III Ex Nic with Firmware 4.8.200</div><div><br></div><div>Any thoughts on this would be greatly appreciated.</div><div><br></div><div>Thanks,</div><div>Adit</div><div>
