/*
* uAnytun
*
* uAnytun is a tiny implementation of SATP. Unlike Anytun which is a full
* featured implementation uAnytun has no support for multiple connections
* or synchronisation. It is a small single threaded implementation intended
* to act as a client on small platforms.
* The secure anycast tunneling protocol (satp) defines a protocol used
* for communication between any combination of unicast and anycast
* tunnel endpoints. It has less protocol overhead than IPSec in Tunnel
* mode and allows tunneling of every ETHER TYPE protocol (e.g.
* ethernet, ip, arp ...). satp directly includes cryptography and
* message authentication based on the methodes used by SRTP. It is
* intended to deliver a generic, scaleable and secure solution for
* tunneling and relaying of packets of any protocol.
