Anas Nashif fe958df4dd libc: rework libc selection and reduce Kconfigs Moved all libc Kconfigs to where the code is and remove the default Kconfig for selecting the minimal libc. Minimal libc is now the default if nothing else is configured in. Removed the options for extended libc, this obviously was restricting features in the minimal libc without a good reason, most of the functions are available directly when using newlib, so there is no reason why we need to restrict those in minimal libc.

Description
===========

zperf is a network traffic generator for Zephyr that may be used to
evaluate network bandwidth.

Features
=========

- Compatible with iPerf_2.0.5.
- Client or server mode allowed without need to modify the source code.
- Working with task profiler (PROFILER=1 to be set when building zperf)

Supported Boards
================

zperf is board-agnostic. However, zperf requires a network interface.
So far, zperf has been tested only on the Intel Galileo Development Board.

Usage
=====

If the zephyr is a client, then you can start the iperf in host with these
command line options if you want to test UDP:

$ iperf -s -l 1K -u -V -B 2001:db8::2

In zephyr start zperf like this

zperf> udp.upload 2001:db8::2 5001 10 1K 1M

or if you have set the zephyr and peer host IP addresses in config file,
then you can simply say

zperf> udp.upload2 v6 10 1K 1M


If the zephyr is acting as a server, then first start zephyr in download
mode like this:

zperf> udp.download 5001

and in host side start iperf like this

$ iperf -l 1K -u -V -c 2001:db8::1 -p 5001

Note the you might need to rate limit the output using -b option
if zephyr is not able to receive all the packets in orderly manner.
