Could you illuminate what issue this patch was fixing? I understand the PMD works at the driver layer, for delivery of L2 packets. It does not own the responsibility to keep order(the responsibility lies wi= th the protocol stack, like TCP)? http://patches.dpdk.org/patch/16665/ Best regards, Gavin IMPORTANT NOTICE: The contents of this email and any attachments are confid= ential and may also be privileged.
