From e65775fdd389e4f47eb1972ef6372e20c6c2cc05 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Thu, 9 Jun 2022 11:17:14 -0400 Subject: [PATCH] Documentation: add description for net.sctp.intl_enable Describe it in networking/ip-sysctl.rst like other SCTP options. We need to document this especially as when using the feature of User Message Interleaving, some socket options also needs to be set.
