Ubuntu系统中Realtek网卡（r8169驱动）频繁断网的求助

各位大佬，实在被逼得没办法了来求助！我的Ubuntu现在完全没法正常用，以太网每隔20分钟到1小时就会突然消失，每次都得重启电脑才能重新连上网络，这效率低得让人抓狂！

我一开始以为是内置网卡坏了——我的内置网卡是Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)，于是特意买了个TP-LINK的TG-3468独立网卡，结果没想到俩网卡居然都用的是同一个r8169内核模块，而且问题完全一样，看来是这个驱动模块出大问题了…

另外说一下，这个问题在Ubuntu 23.04和23.10两个版本上都存在，不是某个版本的特例。

下面是我的网卡驱动详细信息：

driver: r8169
version: 6.5.7-x64v3-xanmod1
firmware-version: rtl8168h-2_0.0.2 02/26/15
expansion-rom-version:
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

我还抓取了断网时的系统日志，是通过命令获取的：
