Merge branch 'documentation-add-description-for-a-couple-of-sctp-sysctl-options'
Xin Long says:
====================
Documentation: add description for a couple of sctp sysctl options
These are a couple of sysctl options I recently added, but missed adding
documents for them. Especially for net.sctp.intl_enable, it's hard for
users to setup stream interleaving, as it also needs to call some socket
options.
This patchset is to add documents for them.
