[ns] Class parameter setup problem

[jmentz <jmentz@cs.uct.ac.za>]

Hi, the following scenario illustrates a problem that I have been having
throughout my scripts:

	Application/Traffic/CBR set packet_size 1000

	set cbr0 [new Application/Traffic/CBR]

	puts "CBR packet size = [$cbr0 set packet_size_]"

My understanding is that line one should modify the CBR class parameters
so that all subsequent instances are created with a packet size of
1000.  This is not the case and both line 3 as well as the nam scripts
suggest that line one has no efect.

Any ideas as to the cause of this?
