    如题，上一版内核和目前版本内核区别

    开源驱动根据#if (LINUX_VERSION_CODE >= KERNEL_VERSION(6, 13, 0))判断，导致识别API错误。以下是个人强制修复patch代码，但是对于非驱动开发工程师来说，应该比较难理解。非常不建议合并新驱动修改API.

    把 #if (LINUX_VERSION_CODE >= KERNEL_VERSION(6, 13, 0)) 修改为 #if (LINUX_VERSION_CODE >= KERNEL_VERSION(6, 12, 65)) 更好吧

    支持别的无线网卡导致的问题，预计下个版本在6.12.66修复
