docs: Dummy pre-configured results
In case of Dummy traffic generator, the test results can be pre-configured. Configuration and examples were described in trafficgen related chapter.

-------------
+Dummy
+-----
+
+The Dummy traffic generator can be used to test VSPERF installation or
+to demonstrate VSPERF functionality at DUT without connection
+to a real traffic generator.
+
+You could also use the Dummy generator in case, that your external
+traffic generator is not supported by VSPERF. In such case you could
+use VSPERF to setup your test scenario and then transmit the traffic.
+After the transmission is completed you could specify values for all
+collected metrics and VSPERF will use them to generate final reports.
+

To select the Dummy generator please add the following to your
custom configuration file ``10_custom.conf``.

+Dummy result pre-configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In case of a Dummy traffic generator it is possible to pre-configure the test
+results. This is useful for creation of demo testcases, which do not require
+a real traffic generator. Such testcase can be run by any user and it will still
+generate all reports and result files.
+
+Result values can be specified within ``TRAFFICGEN_DUMMY_RESULTS`` dictionary,
+where every of collected metrics must be properly defined. Please check the list
+of traffic-type-metrics_.
+
+Dictionary with dummy results can be passed by CLI argument ``--test-params``
+or specified in ``Parameters`` section of testcase definition.
+
+Example of testcase execution with dummy results defined by CLI argument:
+
+.. code-block:: console
+
+ $ ./vsperf back2back --trafficgen Dummy --test-params \
+ "TRAFFICGEN_DUMMY_RESULTS={'b2b frames':'3000','b2b frame loss %':'0.0'}"
+
+Example of testcase definition with pre-configured dummy results:
+
+.. code-block:: python
+
+ {
+ "Name": "back2back",
+ "Traffic Type": "rfc2544_back2back",
+ "Deployment": "p2p",
+ "biDirectional": "True",
+ "Description": "LTD.Throughput.RFC2544.BackToBackFrames",
+ "Parameters" : {
+ 'TRAFFICGEN_DUMMY_RESULTS' : {'b2b frames':'3000','b2b frame loss %':'0.0'}
+ },
+ },
+**NOTE:** Pre-configured results for the Dummy traffic generator will be used only
+in case, that the Dummy traffic generator is used. Otherwise the option
+``TRAFFICGEN_DUMMY_RESULTS`` will be ignored.
