When the NIC receives a packet with an invalid ICRC checksum, the packet is discarded. I know that it is possible to configure the NIC to ignore the ICRC checksum. I am using a ConnectX-5. What tools/commands in the OFED should I use to disable (skip) ICRC check checksum validation?
Thank you for posting your inquiry on the Mellanox Community.
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.
