Subject: [PATCHv2 net 2/3] Documentation: add description for net.sctp.intl_enable
Date: Thu, 9 Jun 2022 11:17:14 -0400 [thread overview]
Message-ID: <2792d34dbac5750f23854bdb042f03f63d3fa918.1654787716.git.lucien.xin@gmail.com> (raw)
In-Reply-To: <cover.1654787716.git.lucien.xin@gmail.com>
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.
Fixes: 463118c34a35 ("sctp: support sysctl to allow users to use stream interleave")
