[ns] a problem of packet disorder

[sjdong <sjdong@telekbird.com.cn>]

hi,all
 I emulaite packet disorder,I give every packet a random delay,the following
 is what I do:

 in delay.cc
   delay_=rand();
 in ns-link.tcl
    SimpleLink instproc init { src dst bw q {lltype "DelayLink"} } {
    #$link_ set delay_ $delay
  //
  //I delete delay,because I don't want to give a constant delay
  //
 so in my own program
  $ns simplex-link $node0 $node1 100Mb DropTail

 after recompile,the error is "no given value for qtype"
 who can tell me why?
 thx a lot
