Reto Schneider 7eabab2f5d samples, tests: Use semi-accurate project names When using an IDE (e.g. Eclipse, Qt Creator), the project name gets displayed. This greatly simplifies the navigation between projects when having many of them open at the same time. Naming every project "NONE" defeats this functionality. This patch tries to use sensible project names while not duplicating too much of what is already represented in the path. This is done by using the name of the directory the relevant CMakeLists.txt file is stored in. To ensure unique project names in the samples (and again, in the tests folder) folder, small manual adjustments have been done.

Network Statistics Sample Application
#####################################

Overview
********

This sample shows how to query (and display) network statistics from a user
application.

The source code for this sample application can be found at:
:file:`samples/net/stats`.

Requirements
************

- :ref:`networking_with_qemu`

Building and Running
********************

A good way to run this sample application is with QEMU as described in
:ref:`networking_with_qemu`.

Follow these steps to build the network statistics sample application:

.. zephyr-app-commands::
   :zephyr-app: samples/net/stats
   :board: <board to use>
   :conf: prj.conf
   :goals: build
   :compact:

If everything is configured correctly, the application will periodically print
current network statistics to the console.
