Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
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.

LLDP Sample Application
#######################

Overview
********

The Link Layer Discovery Protocol sample application for Zephyr will enable
LLDP support and setup VLANs if needed.

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

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

- :ref:`networking_with_host`

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

A good way to run this sample LLDP application is inside QEMU,
as described in :ref:`networking_with_qemu` or with embedded device like
FRDM-K64F. Note that LLDP is only supported for boards that have an ethernet
port.

Follow these steps to build the LLDP sample application:

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

Setting up Linux Host
=====================

If you need VLAN support in your network, then the
:zephyr_file:`samples/net/vlan/vlan-setup-linux.sh` provides a script that can be
executed on the Linux host. It creates two VLANs on the Linux host and creates
routes to Zephyr.
