Hello,

this is the right behaviour, the API can't flush away layers information just after the compilation (or after the packet was sent) because it is often useful to compile/send multiple times the same packet with some change (or even the same packet). For example to implement traceroute, a natural implementation will create the packet only the first time, than modify the layers to change the ip ttl and (udp|tcp) port, recompile than resend the packet, until the work is done.

ars_destroy() is provided as a way to reuse the same packet structure to build a new layer without allocate a new one to send multiple, different packets.

Ciao,
Salvatore
