From 8e0c3b73cec1b943affde91b3c412ad8266b4694 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 15 Dec 2017 00:41:26 +0800 Subject: sctp: implement generate_ftsn for sctp_stream_interleave generate_ftsn is added as a member of sctp_stream_interleave, used to create fwdtsn or ifwdtsn chunk according to abandoned chunks, called in sctp_retransmit and sctp_outq_sack. sctp_generate_iftsn works for ifwdtsn, and sctp_generate_fwdtsn is still used for making fwdtsn.
