303 An SCTP socket will only have one peer label assigned to it. This will be
305 associations on this socket will have their packet peer label compared to
308 socket peer sid against the received packets peer sid to determine whether
316 (multi-homing) on a single socket, it is possible to configure policy
318 socket peer label is determined by the first associations transport
328 label (see **netlabel-config**\(8) helper script for details).
