SCTP stack (RFC4960)
== CONTENT ==
* SCTP chunks definition as per RFC4960;
* Helper functions to set/get values to/from the corresponding chunks;
* Hooks to the session/application layers;
* Complete state-machine handling;
* Implementation for unexpected chunk received in a certain
state (state-machine error handling)
* Support for 1-single connection;
* Sample application to test receive/transmit data-path;
* Test to validate SCTP stack;
