The Issue is to handle Scaler v8.2-385 (baf7f3a) on Dell R750xs server, the 10G NIC card is Broadcom BCM57412 NetXtreme-E 10Gb SFP+. Firmware is the latest, but driver is not. The symptom is that only one port or no port could be recognized. After patch, all port in the Quad-Port 10GbE SFP+ could be recognized. For the time being this is a workaround and manual installation is required. It requires significant effort to port to 4.14 kernel.

        本次需求是处理 Dell R750xs 服务器上的 Scaler v8.2-385 (baf7f3a)，网卡是 Broadcom BCM57412 NetXtreme-E 10Gb SFP+。 固件是最新的，但驱动程序不是。 故障现象是只能识别一个端口或无法识别端口。 打补丁后，Quad-Port 10GbE SFP+的所有端口都可以识别了。目前这是一种解决方法，需要手动安装。 移植到 4.14 产品内核需要付出很大的努力。

        看Kernel log Driver在init 0000:98:00.0和0000:ca:00:00.1就報error了，连device node都沒有

        正常来一块网卡会有两个网口，enp202s0f0和enp202s0f1，但是下图只识别出来一个port
