From 3c6a976325f32f880b7e53f50ebe86fa0e8476c9 Mon Sep 17 00:00:00 2001 From: Marco Varlese Date: Thu, 1 Mar 2018 11:19:59 +0100 Subject: SCTP: API to add a sub-connection This patch adds an API to add a sub-connection following a SRC/DST IP mapping as required by the RFC4960. At the same time, it changes the way the next available sub-connection is being calculated: rather than having an index in the parent connection which is prone to many issues at run-time, the next available sub-connection is being calculated by looking at the state of the set sub-connections and if marked as DOWN it means that is an available slot to be used.
