Jukka Rissanen 86689030e8 net: Clarify logging in networking code Remove network specific default and max log level setting and start to use the zephyr logging values for those. Remove LOG_MODULE_REGISTER() from net_core.h and place the calls into .c files. This is done in order to avoid weird compiler errors in some cases and to make the code look similar as other subsystems.

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.
