+ * For more flexible selection of shapping algorithm in different network

+ * firmware to recalculate shapping parameters. However, whether the parameters

+ * the calculation of shapping parameters, such as on network engine with
+ * revision id 0x21, the value driver calculated will be used to configure to
+ * hardware. On the contrary, firmware ignores configuration of driver
+ * and recalculates the parameter.
