Enable LLDP support and setup VLANs.
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

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

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.
