    主机是yoga 7i 12700H，没有网卡。以前系统是20.9, 用usb3.0 线把thunderbolt 口连到p32p-30 的thunderbolt口，就自动识别到了 p32p-30 带的网卡，现在安装了v23, 找不到网卡了。

    把P32p-30 连到 macbook pro，看到wired network, 证明 p32p-30 ，没有问题。问题就在 deepin.

    这是在mackbook 里面看到的usb 转 网卡的信息

    给内核加了启动参数

    pcie_ports=compat

    连上显示器再启动，ip a 会显示这个：

    lspci -v 显示：
