Subject: [dpdk-stable] [PATCH 11/24] net/hns3: get PCI revision ID
Date: Mon, 17 Aug 2020 17:25:19 +0800
Message-ID: <20200817092532.59530-12-huwei013@chinasoftinc.com> (raw)
In-Reply-To: <20200817092532.59530-1-huwei013@chinasoftinc.com>

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

[ upstream commit 837740cfa37a4641b6e3fc2d92c6572fe3c9911f ]

The hns3 network engine is built-in multiple SoCs, such as kunpeng 920,
kunpeng 930, etc. The PCI revision id is 0x21 in kunpeng 920, and the PCI
revision id is 0x30 in kunpeng 930.

This patch gets PCI revision to identify different version of hardware
network engine.
