+ 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.
+
+ If you say N here, you will get the standard packet scheduler, which
+ is a FIFO (first come, first served). If you say Y here, you will be
+ able to choose from among several alternative algorithms which can
+ then be attached to different network devices. This is useful for
+ example if some of your network devices are real time devices that
+ need a certain minimum data flow rate, or if you need to limit the
+ maximum data flow rate for traffic which matches specified criteria.
+ This code is considered to be experimental.
+
+ To administer these schedulers, you'll need the user-level utilities
+ from the package iproute2+tc at
+ <https://www.kernel.org/pub/linux/utils/net/iproute2/>. That package
+ also contains some documentation; for more, check out
+ <http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2>.
+
+ This Quality of Service (QoS) support will enable you to use
+ Differentiated Services (diffserv) and Resource Reservation Protocol
+ (RSVP) on your Linux router if you also say Y to the corresponding
+ classifiers below. Documentation and software is at
+ <http://diffserv.sourceforge.net/>.
+
+ If you say Y here and to "/proc file system" below, you will be able
+ to read status information about packet schedulers from the file
+ /proc/net/psched.
+
+ The available schedulers are listed in the following questions; you
+ can say Y to as many as you like. If unsure, say N now.
