Subject: [dpdk-dev] [PATCH v2 6/9] net/hns3: set max scheduling rate based on actual board
Date: Tue, 29 Sep 2020 20:01:14 +0800 [thread overview]
Message-ID: <20200929120117.50394-7-huwei013@chinasoftinc.com> (raw)
In-Reply-To: <20200929120117.50394-1-huwei013@chinasoftinc.com>
From: Huisong Li <lihuisong@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.
