======================================================
Netlink specification support for raw Netlink families
======================================================
This document describes the additional properties required by raw Netlink
families such as ``NETLINK_ROUTE`` which use the ``netlink-raw`` protocol
specification.
Specification
=============
The netlink-raw schema extends the :doc:`genetlink-legacy <genetlink-legacy>`
schema with properties that are needed to specify the protocol numbers and
multicast IDs used by raw netlink families. See :ref:`classic_netlink` for more
information.
Globals
-------
protonum
~~~~~~~~
The ``protonum`` property is used to specify the protocol number to use when
opening a netlink socket.

Multicast group properties
--------------------------
value
~~~~~
The ``value`` property is used to specify the group ID to use for multicast
group registration.
.. code-block:: yaml
mcast-groups:
