+Notes:
+       1)Only handles one LTP "connection". There isn't a good way to separate
+               different LTP "connections" from new sessions of the same "connection".
+               Use Tcpdump filters to separate connections. Libpcap filtering could also
+               be added in ltp2tcp.
+       2)Uses some special types from Linux (u_char, u_int32_t)
