Sebastian Bøe 55ee53ce91 cmake: Prepend 'cmake_minimum_required()' into 'app' build scripts
Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.

Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.

To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.

This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.

The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

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:
:file:`samples/net/lldp`.

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

- :ref:`networking_with_qemu`

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
: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.
