Realtek 8168驱动在Linux内核6.5.0-15-generic下编译失败及DKMS安装异常求助
大家好，我在Ubuntu 22.04 LTS上遇到了Realtek 8168网卡驱动的棘手问题——官方源里的r8168-dkms（版本8.049.02）在6.5.0-15-generic内核下编译失败，尝试手动安装Realtek官方的8.052.01版本驱动也碰到了DKMS相关的异常。下面是详细的问题信息，希望能得到大家的帮助！
网卡硬件信息
我的网卡型号如下：
lspci | grep Ethernet 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
官方源驱动编译失败日志
执行cat /var/lib/dkms/r8168/8.049.02/build/make.log查看编译日志，核心错误是函数未声明和类型转换警告被当作错误：

手动安装官方驱动的DKMS异常
我尝试安装Realtek官方的8.052.01版本驱动，先删除了旧的DKMS记录：
sudo rm -rf /var/lib/dkms/r8168/8.052.01/ sudo rm -rf /var/lib/dkms/r8168/
但执行编译命令时出现错误：
sudo dkms build r8168/8.052.01 --force
输出如下：
Kernel preparation unnecessary for this kernel. Skipping... Building module: cleaning build area... make -j12 KERNELRELEASE=6.5.0-15-generic...(bad exit status: 2) Error! Bad return status for module build on kernel: 6.5.0-15-generic (x86_64) Consult /var/lib/dkms/r8168/8.052.01/build/make.log for more information.
查看该日志cat /var/lib/dkms/r8168/8.052.01/build/make.log，发现是Makefile缺失对应规则：
DKMS make.log for r8168-8.052.01 for kernel 6.5.0-15-generic (x86_64) Tue Feb 6 10:45:03 AM AST 2024 make -C src/ clean make -C src/ modules make -C src/ install make[1]: Entering directory '/var/lib/dkms/r8168/8.052.01/build/src' make[1]: Entering directory '/var/lib/dkms/r8168/8.052.01/build/src' make[1]: *** No rule to make target 'clean'. Stop. make[1]: *** No rule to make target 'modules'.

尝试指定内核版本编译也失败，提示同样的Makefile规则缺失问题：
sudo dkms build r8168 -v 8.052.01 -k 6.5.0-15-generic --force
其他相关发现和已执行操作
- 之前发现从Windows 10直接重启到Ubuntu时，网卡会工作异常；后来在Windows上安装了Realtek 10.69版本驱动后，再重启到Ubuntu就没有这个问题了。
- 我本来想给
r8168-dkms提交bug，但发现它不是官方包。 - 我曾为6.5.0-14-generic内核成功手动安装过8.052.01驱动，步骤如下：
- 移除旧驱动：
sudo dkms remove r8168/8.049.02 --all - 解压驱动包：
tar xvf r8168-8.052.01.tar.bz2 - 进入源码目录：
cd r8168-8.052.01/src - 创建DKMS源码目录：
sudo mkdir /usr/src/r8168-8.052.01 - 复制源码文件：
sudo cp -v * /usr/src/r8168-8.052.01/ - 创建
dkms.conf文件：sudo nano /usr/src/r8168-8.052.01/dkms.conf，内容为：PACKAGE_NAME="r8168" PACKAGE_VERSION="8.052.01" BUILT_MODULE_NAME[0]="$PACKAGE_NAME" DEST_MODULE_LOCATION[0]="/updates/dkms" AUTOINSTALL="YES" REMAKE_INITRD="YES" - 执行DKMS命令：
sudo dkms add r8168/8.052.01 sudo dkms build r8168/8.052.01 -k 6.5.0-14-generic sudo dkms install r8168/8.052.01 -k 6.5.0-14-generic
- 移除旧驱动：
求助问题
现在我卡在两个核心问题上：
- 官方源的
r8168-dkms8.049.02版本无法在6.5.0-15-generic内核编译，核心错误是skb_gso_segment函数未声明，同时const类型转换的警告被当作错误处理。 - 手动安装的8.052.01版本驱动在DKMS编译时提示Makefile没有clean、modules等规则，无法完成编译。
请问有没有办法解决这两个问题？或者有没有其他方式让我的Realtek 8168网卡在6.5.0-15-generic内核下正常工作？
