[ns] How to modify packet header?

[Zhenqiang Ye <yyzzqq001@yahoo.com>]

Dear all:
  In my simulation, I add one variable into the DSR
packet header (/dsr/hdr_sr.h)

  //old part
   .................
  int rtreq_seq_ ;
  int max_propagation_;
  int route_reply_;
   ..................

---------------------------------

  //new part 
  .................
  int rtreq_seq_ ;

   //new variable 
  int first_hop_;

  int max_propagation_;
   int route_reply_;
   ..................

  When I run my program, I found that the variable
mapping relationship changed. After the access
function 

  hdr_sr *srh = hdr_sr::access(p.pkt);

  srh->route_reply() will return the value of
max_rpopagation_, not route_reply_. Is there anyone
has the similar trouble before? Any reply will be
appreciated.

Frank
