From 132282386f5d0eff7a84a119599216b5f9e9bfc6 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 8 Dec 2017 21:04:09 +0800 Subject: sctp: add support for the process of unordered idata Unordered idata process is more complicated than unordered data: - It has to add mid into sctp_stream_out to save the next mid value, which is separated from ordered idata's. - To support pd for unordered idata, another mid and pd_mode need to be added to save the message id and pd state in sctp_stream_in. - To make unordered idata reasm easier, it adds a new event queue to save frags for idata. The patch mostly adds the samilar reasm functions for unordered idata as ordered idata's, and also adjusts some other codes on assign_mid, abort_pd and ulpevent_data for idata.
