   4  * The secure anycast tunneling protocol (satp) defines a protocol used
   5  * for communication between any combination of unicast and anycast
   6  * tunnel endpoints.  It has less protocol overhead than IPSec in Tunnel
   7  * mode and allows tunneling of every ETHER TYPE protocol (e.g.
   8  * ethernet, ip, arp ...). satp directly includes cryptography and
   9  * message authentication based on the methodes used by SRTP.  It is
  10  * intended to deliver a generic, scaleable and secure solution for
  11  * tunneling and relaying of packets of any protocol.
