From: Huisong Li <lihuis...@huawei.com> Currently, max scheduling rates configuration of pg, pri and port are set to 100000Mbps, which is the maximum bandwidth of hns3 network engine with revision_id equals 0x21. However, max scheduling rate configuration should be set to hardware based on the actual hardware board environment.
The max_tm_rate in struct hns3_hw, meaning the rate, is obtained from firmware. So we should use the variable to configure the max scheduling rate.
