【问题描述】：

POLICED 表示限制进入包的速度，超过的包将被丢弃。

我在 include/linux/netdevice.h 中看到一条评论“skb 被警察枪杀”。

当然是一样的，但是这个名字背后有什么故事吗？

是的-

menuconfig NET_SCHED
        bool "QoS and/or fair queueing"
        select NET_SCH_FIFO
        ---help---
          When the kernel has several packets to send out over a network
          device, it has to decide which ones to send first, which ones to
          delay, and which ones to drop. This is the job of the queueing
          disciplines, several different algorithms for how to do this
          "fairly" have been proposed.

config NET_ACT_POLICE
        tristate "Traffic Policing"
        depends on NET_CLS_ACT 
        ---help---
          Say Y here if you want to do traffic policing, i.e. strict
          bandwidth limiting. This action replaces the existing policing
          module.

          To compile this code as a module, choose M here: the
          module will be called act_police.
