RK3568J为什么lspci没有信息

准确来说，是根据官方给的源码编译的，但是我也试了官方固件和自己编译出来的一样，啥也没有。
我还有一块瑞芯微RK3588X0的板子，他的lspci 的信息如下

他多了一个Ethernet controller，这个用的就是r8168，我如果想RK3568J和这个一样，我该怎么做？
我有试过在RK3568J的源码里，config配置取消掉stmmac改为realtek，但是应该是没匹配上 接什么设备？接到哪里？m2 pcie ？ 板蓝根 发表于 2024-8-12 13:48
接什么设备？接到哪里？m2 pcie ？
就是自带的网口，我想跑igh接ethercat从站，要替换网卡驱动 我们自带的网口不是 pcie 接口的，当然 lspci 找不到啊 板蓝根 发表于 2024-8-12 18:01

那请问一下，自带的接口是使用的什么驱动，我之前在瑞芯微板子上跑的就是上面我发的，用的是r8168驱动，就可以内核里先配置取消加载，然后加载igh的网卡驱动进行通信。
我如果想和这个进行差不多的操作，所以想找到RK3568那两个网口使用的网卡驱动，然后替换掉
