Sctp shutdown

WebbSCTP Shutdown Features SCTP Shutdown uses a 3-message procedure to allow graceful shutdown, where each endpoint has confirmation of the DATA chunks received by the remote endpoint prior to completion of the shutdown. An Abort procedure is also provided for error cases when an immediate shutdown must take place. WebbSCTP then sends all the data still in its buffers, and then sends a SHUTDOWN chunk. When the other end receives the SHUTDOWN, it will stop accepting data from the application and finish sending all the data. Once it has gotten all the SACK's for the data, it will send a SHUTDOWN ACK chunk and once the closing side has received this chunk, it ...
