[PATCH net-next 4/5] net: hns3: add support to utilize the firmware calculated shaping parameters
From: Huazhong Tan
Date: Fri Nov 20 2020 - 04:17:33 EST
From: Yonglong Liu <liuyonglong@xxxxxxxxxx>
Since the calculation of the driver is fixed, if the number of
queue or clock changed, the calculated result may be inaccurate.
So for compatible and maintainable, add a new flag to tell the
firmware to calculate the shaping parameters with the specified
rate.
