+Nested struct definitions
+-------------------------
+
+Many raw netlink families such as :doc:`tc<../../networking/netlink_spec/tc>`
+make use of nested struct definitions. The ``netlink-raw`` schema makes it
+possible to embed a struct within a struct definition using the ``struct``
+property. For example, the following struct definition embeds the
+``tc-ratespec`` struct definition for both the ``rate`` and the ``peakrate``
+members of ``struct tc-tbf-qopt``.
+
+.. code-block:: yaml
+
+ -
+ name: tc-tbf-qopt
+ type: struct
+ members:
+ -
+ name: rate
+ type: binary
+ struct: tc-ratespec
+ -
+ name: peakrate
+ type: binary
+ struct: tc-ratespec
+ -
+ name: limit
+ type: u32
+ -
+ name: buffer
+ type: u32
+ -
+ name: mtu
+ type: u32
