We are working on RDMA data transfer from custom ZynqMP-SOC platform to server PC(OS-CantOS-8 stream) with mellanox connect-x5 NIC card.
We are performing RDMA write operation from ZynqMP-SOC platform to server PC.
We would like to know on debugging techniques available using Mellanox OFED-stack/ethtool applications on the server PC. I have the following questions on the same.
- Is it possible to reset hw_counter,ethtool statistics without disconnecting ethernet link. If “YES”, can you please share procedure for the same?
- How to find total number of ROCE packets recieved on the Mellanox side?
- How to find NACK packets sent from Mellanox?
- How to find number of error packets received on Mellanox side?
Could you please help us to understand above questions?
Thanks and Regards,
