* It is recommended to set the correct network size because some Wi-SUN network configuration parameters are
* adjusted based on the selected network size. A network configured for a small amount of devices may not work
* optimally for large number of devices. This is because the network bandwidth is divided with all the devices in

* The network size is measured as hundreds of devices that are expected to join to the network. For example,
* for a 400-device network set network size to 4. The Wi-SUN stack will internally use one of the four possible
* configuration buckets based on the selected network size and data rate. The configuration buckets are defined
* for a small, medium, large and xlarge networks.
* for a 400-device network set network size to 4.
*
* For example, with 150kbs data rate set network size to:
* - 1 to use small configuration bucket.
* - 8 to use medium configuration bucket.
* - 15 to use large configuration bucket.
* - 25 to use xlarge configuration bucket.
* The Wi-SUN stack will automatically adjust timing and RPL configuration values based on the selected network
* size and data rate. If a customized timing or RPL values are needed, the APIs below should be invoked after
* changing the network size:
* - set_timing_parameters() to set timing settings to the Wi-SUN interface.
* - rpl_parameters_set() to set RPL settings to the Border Router interface.
*
* By default Wi-SUN stack is configured to use medium sized network.
* By default the Wi-SUN stack is configured to use a few hundreds of devices.
*
* The network size should be set to 0 when running certification tests.
*
* When the network size is changed, it will override all or some of the following configuration values:
* - Timing settings set by set_timing_parameters() of the Wi-SUN interface.
* - RPL settings set by rpl_parameters_set() of the Border Router interface.
*
* When the network size is changed, and if timing or RPL values should be other than defaults set by stack for the
* network size, they need to set again using above function calls.
*
* \param network_size Network size in hundreds of devices (e.g. 12 for 1200 devices), 0 for certificate testing.
* \return MESH_ERROR_NONE on success.
* \return MESH_ERROR_UNKNOWN in case of failure.
