[ns] inversed packet order

[Robin Poss <robin@ee.cornell.edu>]

Hello, 
in my simulation I ask to my mobilenode n2 to send 2 packets, say
p1 and after some time p2,  doing an IP broadcast with a ttl of
1, to that only n2's neighbors will receive the packets. 

n1 is one of these neighbors,  and strangely it receives p2
_before_ p1.

This prevents my protocol from working correctly, and so annoys
me. Does anyone know why such a thing happens and what I could
do to avoid it?

Thanks,
