/* SCTP kernel reference Implementation: User API extensions.

* peeloff.c
*
* Distributed under the terms of the LGPL v2.1 as described in
* http://www.gnu.org/copyleft/lesser.txt
*
* This file is part of the user library that offers support for the
* SCTP kernel reference Implementation. The main purpose of this
* code is to provide the SCTP Socket API mappings for user
* application to interface with the SCTP in kernel.
*
* This implementation is based on the Socket API Extensions for SCTP
* defined in <draft-ietf-tsvwg-sctpsocket-10.txt.
