Cover letter [PATCH net-next v2 00/10] Introduce SCTP Stream Schedulers
This patchset introduces the SCTP Stream Schedulers are defined by
https://tools.ietf.org/html/draft-ietf-tsvwg-sctp-ndata-13
It provides 3 schedulers at the moment: FCFS, Priority and Round Robin. The other 3, Round Robin per packet, Fair Capacity and Weighted Fair Capacity will be added later. More specifically, WFQ is required by WebRTC Datachannels.
The draft also defines the idata chunk, allowing a usermsg to be interrupted by another piece of idata from another stream. This patchset *doesn't* include it. It will be posted later by Xin Long. Its integration with this patchset is very simple and it basically only requires a tweak in sctp_sched_dequeue_done(), to ignore datamsg boundaries.
The first 5 patches are a preparation for the next ones. The most relevant patches are the 4th and 6th ones. More details are available on each patch.
