To avoid hundreds of checks for the different process on I-DATA chunk, struct sctp_stream_interleave is defined as a group of functions used to replace the codes in some place where it needs to do different job according to if the asoc intl_enabled is set. With these ops, it only needs to initialize asoc->stream.si with sctp_stream_interleave_0 for normal data if asoc intl_enable is 0, or sctp_stream_interleave_1 for idata if asoc intl_enable is set in sctp_stream_init. After that, the members in asoc->stream.si can be used directly in some special places without checking asoc intl_enable. make_datafrag is the first member for sctp_stream_interleave, it's used to make data or idata frags, called in sctp_datamsg_from_user. The old function sctp_make_datafrag_empty needs to be adjust some to fit in this ops. Note that as idata and data chunks have different length, it also defines data_chunk_len for sctp_stream_interleave to describe the chunk size.
