ulpevent_data is added as a member of sctp_stream_interleave, used to do the most process in ulpq, including to convert data or idata chunk to event, reasm them in reasm queue and put them in lobby queue in right order, and deliver them up to user sk rx queue. This procedure is described in section 2.2.3 of RFC8260. It adds most functions for idata here to do the similar process as the old functions for data. But since the details are very different between them, the old functions can not be reused for idata. event->ssn and event->ppid settings are moved to ulpevent_data from sctp_ulpevent_make_rcvmsg, so that sctp_ulpevent_make_rcvmsg could work for both data and idata. Note that mid is added in sctp_ulpevent for idata, __packed has to be used for defining sctp_ulpevent, or it would exceeds the skb cb that saves a sctp_ulpevent variable for ulp layer process.

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.
