Both the tracepoint\nand the driver callback consume the complete parameters block, not merely\nreq_type. Do not pass a short individual agreement to the driver.\nBroadcast agreements remain unchanged because they are rejected locally\nafter accessing only req_type.\n\n[edit commit message to not overclaim lack of validation nor\n understate driver impact]",
