A bug was found when multiple SCTP connections were being opened to the same SCTP server. This patch addresses that problem, removing the use of the 'parent' pointer approach for sub-connection and saving instead within the sub-connection itself the ID representing its position. That facilitates pointer-arithmetic to be computed in the get_connection_from_transport(). Change-Id: Iaa1f4efc501590be1c93e42fd6fe3d6e02f635eb Signed-off-by: Marco Varlese <marco.varlese@suse.com>
