If the flow_spec items parsed count does not match the number of items declared in the flow_attr command, or if not all bytes are used for flow_spec items (eg. trailing garbage), a log message is reported and the function leave through the error path. Unfortunately the error code is currently not set. This patch set error code to -EINVAL in such cases, so that the error is reported to userspace instead of silently fail.
