openwrt 23.05编译intel igb5.19.4驱动
- 修改内核配置
make kernel_menuconfig
关闭高端内存
修改内核参数后，要重新编译内核，否则会出莫名错误
make target/linux/clean
make target/linux/install
带上 -j 参数速度会快，如：
-j $(($(nproc)+1)) V=sc
- 下载驱动包，修改Makefile

3. 准备内核
cd ~/openwrt-23.05.5
make target/linux/prepare
make target/linux/compile
- 驱动目录会缺少一个文件kcompat_generated_defs.h，只需要在ubuntu的环境下在src目录make一下就出来，也可以手动建立：
