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.
