Based on your request, unfortunately there is no method of disabling iCRC validation with RoCE v2, as this is an InfiniBand and RoCE Specification requirement, which we do not have control over.RoCE v2 is an internet layer protocol which means that RoCE v2 packets can be routed. Although the RoCE protocol benefits from the characteristics of a converged Ethernet network, the protocol can also be used on a traditional or non-converged Ethernet network. Priority Flow Control (PFC)for the delivery of RoCE across different subnets bringing scalability into the picture.
