Ubuntu18.04上的RTL8152

Question

我刚开始建立一个多功能的网络。我找到了一些很好的USB到2.5GBASE-T适配器。

现在，虽然他们确实用完了盒子，但他们似乎在使用cdc-ncm作为他们的驱动程序，不能充分利用NIC的能力(限制为1500 and，而且性能受到阻碍)。

这是通过为这个芯片安装过时的Realtek驱动程序来解决的。问题是，我需要踢cdc-mbim和cdc-ncm与and探测-r之前附加设备，因为否则模块将冲突和cdc将获胜。但是，我不想只列出这两个模块，因为我也安装了一个使用这些模块的LTE调制解调器。

我的两个问题：

1. 我怎样才能防止cdc-ncm超越设备而不只是撕掉它呢？
2. 如何修补驱动程序以处理最新的内核版本？

系统信息：

• 名称-r: 5.3.8-050308-泛型
• Realtek驱动程序: r8152_2.12.0
• 与cdc-ncm连接后的dmesg输出：

我想通了。我只需将包含的50-usb-realtek-net.rules复制到我的/udev/rules.d中，就可以避免冲突。
