1. 类似的操作在Linux PC上可以成功使用这个wifi么？
2. 你是否有注意过你选择的pcie转wfif的模块是否有DM81xx PCIE RC驱动不支持的特点？

你好！ Chris Meng
我现在一直查找这个问题没有一点头绪，现在想排查是硬件问题还是realtek软件包有问题，
下面是插上了wifi模块后内核启动打印pcie的相关信息如下：

1.首先wifi模块是好的，因为我在一台pc机(自带minipcie接口)上装windows系统，通过驱动精灵安装wifi模块驱动，可以正常使用。
2.因为我想用Realtek的rtl_92ce_92se_92de_8723ae_88ee_linux_mac.驱动包在pc机上编译成x86架构的驱动，很可惜编译不成功，缺少相关的IEEE80211_HW_CONNECTION_MONITOR之类的定义，想通过同样的驱动包来查找是不是我板子pcie硬件有问题，可惜没有编译成功

3.现在想通过做一个自发自收的测试程序loopback，来测试mini pcie硬件是否有问题，请问dvrrdk有自带的测试程序吗？谢谢！
