两张相同的网卡，一张无人认领

我的服务器中有两个相同的网卡，我在其上运行 Proxmox VE。其中一个运行良好unclaimed，另一个运行良好。有人能帮忙吗？据我所知，这unclaimed通常是司机失踪的暗示。但为什么第二张卡有效呢？这可能是硬件故障吗？

感谢您的任何答复！

答案1

看起来一个是控制器，另一个是接口。第二个接口根本没有列出。

根据 AskUbuntu 上的相关回答，Broadcom BCM5720 无法在 Ubuntu 20.04 服务器中工作，这是由驱动程序不匹配触发的，系统错误地使用tg3(Tigon) 驱动程序。

答案提出的解决方案是安装linux-modules-extra软件包并使用bnx2模块而不是tg3.

一旦您拥有bnx2它，它可能会优先于tg3自动加载，或者我们可能必须tg3将bnx2.目前，由于没有可用于测试的卡，我无法判断。

答案2

所以我们最终把它修好了。事实证明，在硬重置和断电后，硬件以某种方式自行修复。tg3实际上是正确的驱动程序，所以它现在可以工作了。感谢@roaima的支持！
