+	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.
