-	It was only designed to work on lower speed links and has design
-	flaws that lead to machine crashes. The qdisc infrastructure in

-Traffic Shaper For Linux
-
-This is the current BETA release of the traffic shaper for Linux. It works
-within the following limits:
-
-o	Minimum shaping speed is currently about 9600 baud (it can only
-shape down to 1 byte per clock tick)
-
-o	Maximum is about 256K, it will go above this but get a bit blocky.
-
-o	If you ifconfig the master device that a shaper is attached to down
-then your machine will follow.
-
-o	The shaper must be a module.
-
-
-Setup:
-
-	A shaper device is configured using the shapeconfig program.
-Typically you will do something like this
-
-shapecfg attach shaper0 eth1
-shapecfg speed shaper0 64000
-ifconfig shaper0 myhost netmask 255.255.255.240 broadcast 1.2.3.4.255 up
-route add -net some.network netmask a.b.c.d dev shaper0
-
-The shaper should have the same IP address as the device it is attached to
-for normal use.
-
-Gotchas:
-
-	The shaper shapes transmitted traffic. It's rather impossible to
-shape received traffic except at the end (or a router) transmitting it.
-
-	Gated/routed/rwhod/mrouted all see the shaper as an additional device
-and will treat it as such unless patched. Note that for mrouted you can run
-mrouted tunnels via a traffic shaper to control bandwidth usage.
-
-	The shaper is device/route based. This makes it very easy to use
-with any setup BUT less flexible. You may need to use iproute2 to set up
-multiple route tables to get the flexibility.
-
-	There is no "borrowing" or "sharing" scheme. This is a simple
-traffic limiter. We implement Van Jacobson and Sally Floyd's CBQ
-architecture into Linux 2.2. This is the preferred solution. Shaper is
-for simple or back compatible setups.

- *
- *
- *	Algorithm:
- *
- *	Queue Frame:
- *		Compute time length of frame at regulated speed
- *		Add frame to queue at appropriate point
- *		Adjust time length computation for followup frames
- *		Any frame that falls outside of its boundaries is freed
- *
- *	We work to the following constants
- *
- *		SHAPER_QLEN	Maximum queued frames
- *		SHAPER_LATENCY	Bounding latency on a frame. Leaving this latency
- *				window drops the frame. This stops us queueing
- *				frames for a long time and confusing a remote
- *				host.
- *		SHAPER_MAXSLIP	Maximum time a priority frame may jump forward.
- *				That bounds the penalty we will inflict on low
- *				priority traffic.
- *		SHAPER_BURST	Time range we call "now" in order to reduce
- *				system load. The more we make this the burstier
- *				the behaviour, the better local performance you
- *				get through packet clustering on routers and the
- *				worse the remote end gets to judge rtts.
- *
- *	This is designed to handle lower speed links ( < 200K/second or so). We
- *	run off a 100-150Hz base clock typically. This gives us a resolution at
- *	200Kbit/second of about 2Kbit or 256 bytes. Above that our timer
- *	resolution may start to cause much more burstiness in the traffic. We
- *	could avoid a lot of that by calling kick_shaper() at the end of the
- *	tied device transmissions. If you run above about 100K second you
- *	may need to tune the supposed speed rate for the right values.
- *
- *	BUGS:
- *		Downing the interface under the shaper before the shaper
- *		will render your machine defunct. Don't for now shape over
- *		PPP or SLIP therefore!
- *		This will be fixed in BETA4
- *
- * Update History :
- *
- *              bh_atomic() SMP races fixes and rewritten the locking code to
- *              be SMP safe and irq-mask friendly.
- *              NOTE: we can't use start_bh_atomic() in kick_shaper()
- *              because it's going to be recalled from an irq handler,
- *              and synchronize_bh() is a nono if called from irq context.
