Unix socket interface for C++ raw IP/IP6/UDP/TCP, layer 2 framework

usi++ (UNIX Socket Interface) is a low-level network-library for sending/receiving IP, IP6, ARP etc. packets directly on RAW or PACKET sockets. It can also be used for network-monitoring and rapid development of pentesting tools. It requires libpcap and libdnet if you want the Layer2 DNET provider.
