We are evaluating RoCE communication using Pods with vRDMA devices on kubernetes.
To set priority of CNP to 6, we did below command but couldn’t get expected result.
We consider it would be limitation of VFs.
Did we have any misunderstanding or mistakes? (e.g. In fact it was not necessary.)
command to set CNP’s DCSP value
echo 48 > /sys/class/net//ecn/roce_np/cnp_dscp
(Note: we got expected result from PF)
