As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no> |

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:
:zephyr_file:`samples/net/stats`.
Requirements
************
- :ref:`networking_with_host`
Building and Running
********************
A good way to run this sample application is with QEMU or native_posix board
as described in :ref:`networking_with_host`.
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.
