	  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 <ftp://ftp.tux.org/pub/net/ip-routing/>.
	  That package also contains some documentation; for more, check out
	  <http://linux-net.osdl.org/index.php/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/>.

config ADK_LINUX_KERNEL_NET_SCH_CBQ
	tristate "Class Based Queueing (CBQ)"
	select ADK_LINUX_KERNEL_NET_SCHED
	default n
	help
	  Say Y here if you want to use the Class-Based Queueing (CBQ) packet
	  scheduling algorithm. This algorithm classifies the waiting packets
	  into a tree-like hierarchy of classes; the leaves of this tree are
	  in turn scheduled by separate algorithms.

	  See the top of <file:net/sched/sch_cbq.c> for more details.

	  CBQ is a commonly used scheduler, so if you're unsure, you should
	  say Y here. Then say Y to all the queueing algorithms below that you
	  want to use as leaf disciplines.

	  packet scheduling algorithm. See

	  different properties and different algorithm.

	help
	  Say Y here if you want to use the ATM pseudo-scheduler.  This
	  provides a framework for invoking classifiers, which in turn
	  select classes of this queuing discipline.  Each class maps
	  the flow(s) it is handling to a given virtual circuit.
