Reto Schneider 7eabab2f5d samples, tests: Use semi-accurate project names When using an IDE (e.g. Eclipse, Qt Creator), the project name gets displayed. This greatly simplifies the navigation between projects when having many of them open at the same time. Naming every project "NONE" defeats this functionality. This patch tries to use sensible project names while not duplicating too much of what is already represented in the path. This is done by using the name of the directory the relevant CMakeLists.txt file is stored in. To ensure unique project names in the samples (and again, in the tests folder) folder, small manual adjustments have been done.

IPv4 autoconf client application
################################

Overview
********

This sample application starts a IPv4 autoconf and self-assigns
a random IPv4 address in the 169.254.0.0/16 range, it defends
the IPv4 address and resolves IPv4 conflicts if multiple
parties try to allocate an identical address.

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

- :ref:`networking_with_qemu`

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

These are instructions for how to use this sample application running
on a :ref:`frdm_k64f` board to configure a link local IPv4 address and
connect to a Linux host.

Connect ethernet cable from a :ref:`Freedom-K64F board <frdm_k64f>` to a Linux
host machine and check for new interfaces.

Running Avahi client in Linux Host
==================================

Assign a IPv4 link local address to the interface in the Linux system

.. code-block:: console

   $ avahi-autoipd --force-bind -D eth0


FRDM_K64F
=========

Build Zephyr the ``samples/net/ipv4_autoconf`` application using these
steps:

.. zephyr-app-commands::
   :zephyr-app: samples/net/ipv4_autoconf
   :host-os: unix
   :board: frdm_k64f
   :goals: build flash
   :compact:

Once IPv4 LL has completed probing and announcement, details are shown like this:

.. code-block:: console

   $ sudo screen /dev/ttyACM0 115200

.. code-block:: console

   [ipv4ll] [INF] main: Run ipv4 autoconf client
   [ipv4ll] [INF] handler: Your address: 169.254.218.128

Note that the IP address may change at each self assignment.

To verify the Zephyr application is running and has configured an IP address
type:

.. code-block:: console

   $ ping -I eth1 169.254.218.128
