Re: getting context stats before acutally writing it to wire.

Currently no function exists to do exactly what you want, but you can 
use the advanced interface to pull the packet from the context (along 
with its size). libnet_adv_cull_packet(); will do this for you. You'd 
have to make a corresponding call to libnbet_adv_free_packet(); tho 
since there is an implicit malloc().

If there's enough interest in being able to do this, I'll write a quick 
function libnet_get_packet_size() or something to run through the 
pblock list and get the current packet size without all the extra 
cruft.

The libnet stats stuff is used to track bytes and packets already 
written. That being said, I'll whip up a quick function 
libnet_getpacket_
