Xin Long 4821a076eb sctp: add fair capacity stream scheduler ... As it says in rfc8260#section-3.5 about the fair capacity scheduler: A fair capacity distribution between the streams is used. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to maintain an equal capacity for all streams. The details are implementation dependent. interleaving user messages allows for a better realization of the fair capacity usage. This patch adds Fair Capacity Scheduler based on the foundations added by commit 5bbbbe32a4 ("sctp: introduce stream scheduler foundations"): A fc_list and a fc_length are added into struct sctp_stream_out_ext and a fc_list is added into struct sctp_stream. In .enqueue, when there are chunks enqueued into a stream, this stream will be linked into stream-> fc_list by its fc_list ordered by its fc_length. In .dequeue, it always picks up the 1st skb from stream->fc_list. In .dequeue_done, fc_length is increased by chunk's len and update its location in stream->fc_list according to the its new fc_length. Note that when the new fc_length overflows in .dequeue_done, instead of resetting all fc_lengths to 0, we only reduced them by U32_MAX / 4 to avoid a moment of imbalance in the scheduling, as Marcelo suggested.
