* Fragmented interleave controls how the presentation of messages occur
* for the message receiver. There are three levels of fragment interleave
* defined. Two of the levels effect {@link SctpChannel}, while
* {@link SctpMultiChannel} is effected by all three levels.
*
* <P> This option takes an {@code Integer} value. It can be set to a value
* of {@code 0}, {@code 1} or {@code 2}.
*
* <P> Setting the three levels provides the following receiver
* interactions:
*
* <P> {@code level 0} - Prevents the interleaving of any messages. This
* means that when a partial delivery begins, no other messages will be
* received except the message being partially delivered. If another message
* arrives on a different stream (or association) that could be delivered,
* it will be blocked waiting for the user to read all of the partially
* delivered message.
*
* <P> {@code level 1} - Allows interleaving of messages that are from
* different associations. For {@code SctpChannel}, level 0 and
* level 1 have the same meaning since an {@code SctpChannel} always
* receives messages from the same association. Note that setting an {@code
* SctpMultiChannel} to this level may cause multiple partial
* delivers from different associations but for any given association, only
* one message will be delivered until all parts of a message have been
* delivered. This means that one large message, being read with an
* association identification of "X", will block other messages from
* association "X" from being delivered.
*
* <P> {@code level 2} - Allows complete interleaving of messages. This
* level requires that the sender carefully observe not only the peer
* {@code Association} but also must pay careful attention to the stream
* number. With this option enabled a partially delivered message may begin
* being delivered for association "X" stream "Y" and the next subsequent
* receive may return a message from association "X" stream "Z". Note that
* no other messages would be delivered for association "X" stream "Y"
* until all of stream "Y"'s partially delivered message was read.
* Note that this option effects both channel types. Also note that
* for an {@code SctpMultiChannel} not only may another streams
* message from the same association be delivered from the next receive,
* some other associations message may be delivered upon the next receive.
*
* <P> It is implementation specific whether or not this option is
* supported.
