标题: rk3399pro插入网卡rtl8811au死机
我在rk3399pro上外接无线网卡rtl8811au（与rtl8812au驱动相同，只是没有蓝牙功能），驱动可以正常编译，驱动模块也可以正常加载，从dmesg中可以看出rk3399pro已经正确识别了网卡，但是我用ifconfig wlan1 up指令启动外接无线网卡时会直接导致开发板死机，这个版本的驱动在其他设备上可以正常使用，不知各位是否有解决方案，我是刚接触Linux系统和3399pro开发板，望多指教，万分感谢！附上驱动源码和系统日志

上为已先加载驱动后插入网卡的系统日志，网卡在222.153483时插入，随后系统死机，后续是重启系统的日志

上为不加载驱动插入网卡后的识别情况，可以看出已经正确识别网卡
已附驱动源码，由于上传附件大小限制所以压缩成了多个包，直接解压即可，压缩包中messages文件是系统日志，我在手册上看到3399pro是验证过支持rtl8811au（rtl8812au）的，恳请大家帮我看看是什么问题，感激不尽！
