- Reworked the driver logic around TX/RX to correctly handle the expectations of the underlying 802.15.4 hardware IP. - Fixed a problem with TX always reporting an error to the stack which resulted in constant retries. - Fixed bug in RX to TX transition which would occasionally cause the driver to error the TX. - Changed RX logic to ensure that invalid RX frames were not passed up the stack. - Simplified hardware timer usage to only use TMR3. - Added RX watermark and TMR3 support to fix a hardware problem where the hw IP can get stuck on a receive in noisy environments. - Modified samples/net/echo_client and echo_server kw41z project config files to provide enanced debug visibility into stacks and threads.

Echo Client
###########
Overview
********
The echo-client sample application for Zephyr implements a UDP/TCP client
that will send IPv4 or IPv6 packets, wait for the data to be sent back,
and then verify it matches the data that was sent.
The source code for this sample application can be found at:
:file:`samples/net/echo_client`.
Requirements
************
- :ref:`networking_with_qemu`
Building and Running
********************
There are multiple ways to use this application. One of the most common
usage scenario is to run echo-client application inside QEMU. This is
described in :ref:`networking_with_qemu`.
There are configuration files for different boards and setups in the
echo-client directory:
- :file:`prj_arduino_101.conf`
Use this for Arduino 101 with external enc28j60 ethernet board.
- :file:`prj_bt.conf`
Use this for Bluetooth IPSP connectivity.
- :file:`prj_cc2520.conf`
Use this for devices that have support for IEEE 802.15.4 cc2520 chip.
- :file:`prj_frdm_k64f_cc2520.conf`
Use this for FRDM-K64F board with external IEEE 802.15.4 cc2520 board.
- :file:`prj_frdm_k64f.conf`
Use this for FRDM-K64F board with built-in ethernet.
- :file:`prj_frdm_k64f_mcr20a.conf`
Use this for FRDM-K64F board with IEEE 802.15.4 mcr20a board.
- :file:`prj_qemu_802154.conf`
Use this when simulating IEEE 802.15.4 network using two QEMU's that
are connected together.
- :file:`prj_qemu_cortex_m3.conf`
Use this for ARM QEMU.
- :file:`prj_qemu_x86.conf`
Use this for x86 QEMU.
- :file:`prj_sam_e70_xplained.conf`
Use this for Atmel SMART SAM E70 Xplained board with ethernet.
Build echo-client sample application like this:
.. zephyr-app-commands::
:zephyr-app: samples/net/echo_client
:board: <board to use>
:conf: <config file to use>
:goals: build
:compact:
Cmake can select the default configuration file based on the BOARD you've
specified automatically so you might not always need to mention it.
Running echo-server in Linux Host
=================================
There is one useful testing scenario that can be used with Linux host.
Here echo-client is run in QEMU and echo-server is run in Linux host.
To use QEMU for testing, follow the :ref:`networking_with_qemu` guide.
In a terminal window:
.. code-block:: console
$ sudo ./echo-server -i tap0
Run echo-client application in QEMU:
.. zephyr-app-commands::
:zephyr-app: samples/net/echo_client
:board: qemu_x86
:goals: run
:compact:
