这是一个测试netlink性能的demo，也是实际项目遇到问题时改bianco的一个demon。demo分为两个部分，内核部分，与用户态部分。大致流程是这样：核态开辟多线程不停地往用户态发送数据，用户态接收后处理，不断测试，检测到发送的一个阈值，低于这个阈值时，用户态可以正确接收，高于阈值则可能会出现丢包的现象。-This is a test the netlink performance of the demo, the actual project experience problems change of bianco' s a demon. The demo is divided into two parts, the parts of the kernel, and user state part. Substantially the process is this: nuclear state opens the multi-threaded stop sending data to the user mode, the user mode after receiving processing, and continuously test, sending a threshold value is detected, and below this threshold, the user mode can be received correctly, higher than the threshold value packet loss phenomenon may occur.
