我有一个 WiFi 适配器华硕 USB-AC53 Nano使用我自己编译的rtl88x2bu驱动程序。当我启动计算机时，由于该功能可预测的接口名称通过systemd，我总是得到一个接口名称（wlx+它的MAC地址）。有时，我需要拔下适配器并稍后再重新插入。但随后接口名称更改为wlan0.然后我过去的 WiFi 密码会被 NetworkManager 忽略，因为它通过接口名称来识别网络连接。
重新插入后，我发现以下行指示失败（下面有详细的系统日志；我将 MAC 地址替换为wlxAABBCCDDEEFF）：
wlan0: Network interface 'wlan0' is already up, refusing to rename to 'wlxAABBCCDDEEFF'.
如果我在拔出之前关闭接口rfkill，问题就会消失，即接口重命名将会成功。但每次接口断开连接时都这样做是非常烦人的。 WiFi 适配器应该是可热插拔的，并且我不想禁用接口重命名触发器。
所以我的问题是，可以指示systemd以便在恢复rfkill状态之前完成接口重命名工作吗？或者我可以制作一个脚本，以便每次重新插回适配器时都可以使用它吗？
这是我的系统日志中的摘录。我使用的是 Ubuntu 22.04。

答案1
尝试使用udev规则。
例如，您可以创建一个udev 规则文件直接分配NAME=（例如您可以创建文件 a /etc/udev/rules.d/70-custom-names.rules）。将以下规则添加到规则文件中：
ACTION=="add", SUBSYSTEM=="net", KERNEL=="wlan0", NAME="wlxAABBCCDDEEFF"
如果此解决方案不起作用，则问题可能出在相对于其他 udev 规则的顺序/位置上。
修改后记得重启系统或者尝试使用以下命令避免重启：
udevadm control --reload-rules
我觉得这是解决您的问题的有用链接。
该解决方案适用于自定义 Linux 发行版，遗憾的是我无法在 Ubuntu 发行版上尝试它。
