Hello everyone:

	On FreeBSD with ipfw/dummynet for traffic shaping, one uses the
pipe with:

ipfw pipe 1 config bw size

to set the size of the pipe.  I noticed on Linux, they can set a burst
size so it can burst a x number over the pipe size, is there a similar
setting available?  Also, I noticed for pipes, one can set the queue size
in slots of KBytes, how does one determine what's a good size?
