Anas Nashif ca0ad13a61 net: enable SLIP only on QEMU targets In many networking tests we had to configure SLIP in the prj.conf leaving those configurations Qemu specific. This change enables SLIP for QEMU targets automatically and allows reuse of prj.conf for multiple boards. Additionally, the TUN options is removed. This option was not used anywhere. To enable self-contained networking tests that do not depend on SLIP, we introduce the new option NET_TEST which disables TAP and allows testing in QEMU without the need for a host interface.

CoAP over DTLS sample client
############################

Overview
********
This sample code shows a CoAP over DTLS client using mbedTLS on top of Zephyr.

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

Follow the steps for testing :ref:`networking_with_qemu`.

Run the server application at samples/net/coaps_server, with the following
command:

.. code-block:: console

	make server

In other terminal window, run this client application at samples/net/coaps_client:

.. code-block:: console

	make client

You will get the following output:

.. code-block:: console

	reply: 60 45 00 01 ff 54 79 70 65 3a 20 30 0a 43 6f 64 65 3a 20 31 0a 4d

	00 00 00 00 00 (123 bytes)

From the server application directory the screen should display

.. code-block:: console

	*******
	type: 0 code 1 id 1
	*******
	connection was closed gracefully
	done

If the server does not receive the  messages, restart the app and try to connect
the client again.
