[LiSA-Devel] Libnet package

[Mihaela Alexandra Martinas]

Hi Ionut,

I chose pcap because it was easier than if I had to extract the information
from a raw
packet. For libnet I don't have a real good motivation. I'll try to send
packets using raw sockets
and for receiving I'll keep pcap. Seems a good solution?
