（2）如何解决中断处理程序执行过长和中断丢失的问题： Linux 将中断处理过程分成了两个阶段，也就是上半部和下半部。上半部用来快速处理中断，它在中断禁止模式下运行，主要处理跟硬件紧密相关的或时间敏感的工作。也就是我们常说的硬中断，特点是快速执行。下半部用来延迟处理上半部未完成的工作，通常以内核线程的方式运行。也就是我们常说的软中断，特点是延迟执行。

kernel processing tcp/ip 编程算法

XDP or eXpress Data Path provides a high performance, programmable network data path in the Linux kernel as part of the IO Visor Project. XDP provides bare metal packet processing at the lowest point in the software stack which makes it ideal for speed without compromising programmability. Furthermore, new functions can be implemented dynamically with the integrated fast path without kernel modification. Other key benefits of XDP includes the following:
