assign_number is added as a member of sctp_stream_interleave, used to assign ssn for data or mid (message id) for idata, called in sctp_packet_append_data. sctp_chunk_assign_ssn is left as it is, and sctp_chunk_assign_mid is added for sctp_stream_interleave_1. This procedure is described in section 2.2.2 of RFC8260. All sizeof(struct sctp_data_chunk) in tx path is replaced with sctp_datachk_len, to make it right for idata as well. And also adjust sctp_chunk_is_data for SCTP_CID_I_DATA. After this patch, idata can be built and sent in tx path. Note that if sp strm_interleave is set, it has to wait_connect in sctp_sendmsg, as asoc intl_enable need to be known after 4 shake- hands, to decide if it should use data or idata later. data and idata can't be mixed to send in one asoc.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
