Debian 标准网络接口不起作用,必须使用 USB enx00e04c6803a1

我已经使用 Debian GNU/Linux stable (sid) 五个月了,没有出现任何问题。几天前,我的计算机无法通过 ens33(嵌入式台式机背面的以太网端口)连接,我不得不使用外部 USB 转以太网转换器来连接互联网。当我检查时ifconfig -a,我很震惊,甚至没有条目,ens33并且eth0拒绝运行ifupifdown运行。
ifconfig -a结果:

如何重新添加标准以太网接口?

Debian 正在过渡到可预测的网络接口名称

enp2s0= 以太网控制器、总线 2、插槽 0、第一个且唯一的功能,或者换句话说,PCI 设备 02:00.0。 lspci 输出表明它是 Realtek RTL8101/2/6E。

看起来 RTL8106E 至少需要一两个固件文件:您可能需要firmware-realtek从 Debian 的非自由部分安装该软件包。 (仍然可以在不支付任何费用的情况下使用,但附加一些额外的版权和/或许可条件。)

https://packages.debian.org/unstable/kernel/firmware-realtek

ens33根据系统固件中存储的信息,这意味着 PCIe 热插拔插槽#33;当问题出现时,您是否认为没有必要而禁用了 PCIe 热插拔支持模块?或者当时您是否进行了任何内核更新或配置更改?
