    How to enable DCQCN on ConnectX-3 Pro


      Hello, everyone.

      In the community, I found the method to set the DCQCN parameters on ConnectX-4.

      It writes "adjust the parameters under the path /sys/kernel/debug/kernel/mlx5/".

      However, the method could not be applied to ConnectX-3 Pro. And the path "/sys/class/net/*device name*/ecn" does not exist.

      So how can I enable DCQCN on ConnectX-3 Pro?
