This commit removes deprecated APIs and replaces them with routines that provide similar functionality without the flexibility originally offered by the deprecated APIs. Removing deprecated routines will help us to be prepared once the new IP stack is ready (ZEP-793). Furthermore, this commit will also help us to move our current DNS Client implementation to the lib/iot directory, as specified by ZEP-847. This commit removes the netz library from the DNS client sample application. UDP functionality is replaced by primitive routines. Specifically, the following changes are applied by this patch: - Remove netz routines - Remove app_buf data structure - Introduce primitive data types in the DNS client code - Introduce primitive network routines - Add a header file containing configurable parameters Jira: ZEP-793 Jira: ZEP-847 Change-Id: I0302133da77308f0cdd9ace2c0265e6b77673ff0 Signed-off-by: Flavio Santes <flavio.santes@intel.com> |

DNS Client Application
Requirements
------------
* Ethernet LAN for testing purposes.
* Galileo Gen 2 Development Board.
* USB-UART cable: CH340, FTDI 6-pin or equivalent for debugging.
* dnsmasq application. The dnsmasq version used in this sample is:
dnsmasq -v
Dnsmasq version 2.75 Copyright (c) 2000-2015 Simon Kelley
Building instructions
---------------------
* Read src/tcp_config.h, change the IP addresses according to the LAN
environment.
* make pristine && make are enough to build this sample.
* Follow the steps indicated here:
https://www.zephyrproject.org/doc/board/galileo.html
to load the binary into the Galileo Dev Board.
Usage
-----
* Open a terminal window and type:
dnsmasq -d
* Connect the USB-UART cable to the Galileo. Open a terminal and run:
screen /dev/ttyUSB0 115200
* Connect Galileo to the LAN, Turn on the board.
* The screen terminal window will show:
