Ubuntu 23.10下Lenovo X1 Carbon 9代网络接口频繁重置，dmesg持续输出重复错误求助（附解决方法）

各位大佬好，我最近碰到个闹心的网络问题，折腾了半天终于搞定了，先把问题和解决过程分享出来，给遇到同款问题的朋友提个醒：

我的机器是Lenovo X1 Carbon 9代，装的是Ubuntu 23.10系统，目前有WiFi、Docker和ZeroTier这几个网络相关组件。最近发现每5到10秒，网络接口就会反复重新配置——浏览器里一直弹出“network changed”的错误提示，用dmesg查看内核日志时，还会持续输出重复的内容，具体日志如下：

这类日志会每隔大概10秒就重复一次，循环不停。

我一开始怀疑是ZeroTier的问题，卸载之后发现问题依然存在，而且网上搜了一圈也没找到相关解决方案，实在不知道该从哪里入手排查。

更新：问题已解决

后来我尝试卸载了Kasm Workspace（包括它的Docker镜像），没想到这个网络接口频繁重置的问题就彻底消失了！可惜我现在没时间深入排查具体是Kasm的哪个组件或配置导致的冲突，但还是想把这个解决方法分享出来，希望能帮到遇到同样问题的朋友。
