[ns] Unknown Trace-Lines

[Matthias Budde]

Hi,

My simulation tracefile shows a lot of lines for sent packets wich look like this:

s -t 2.274370457 -Hs 362 -Hd -2 -Ni 362 -Nx 424.64 -Ny 601.31 -Nz 0.00 -Ne 9.978164 -Nl MAC -Nw --- -Ma 0 -Md 18a -Ms 0 -Mt 0 

As far I understand it, those are neither normal (in my simulation i.e. udp) or routing 
packets, because those each have a type set ("-It xxx"). ARP packets have their type set
as well ("-P arp"). 

Does anybody know where the lines come from?

Thanks, best,

-Matt
