From c28445c3cb07ba1da2c1dc7b5f3066c686a6acc6 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Wed, 18 Jan 2017 00:44:45 +0800 Subject: sctp: add reconf_enable in asoc ep and netns This patch is to add reconf_enable field in all of asoc ep and netns to indicate if they support stream reset. When initializing, asoc reconf_enable get the default value from ep reconf_enable which is from netns netns reconf_enable by default. It is also to add reconf_capable in asoc peer part to know if peer supports reconf_enable, the value is set if ext params have reconf chunk support when processing init chunk, just as rfc6525 section 5.1.1 demands.
