[RTEMS/RASP] Networking demo in RTEMS

In order to have the internet application on RTEMS with Raspberry Pi, we first have to check whether the internet works well.

How to find out the mac address??

However, so far I can only print out the information of loopback interface
I think the problem probably comes from our institute internet framework.
Therefore, I prepare a Wi-Fi router to get rid of it.

Ethernet support on RaspPi is stiil an open issue :P

::::::::::::::::::::::::If the internet does work:::::::::::::::::::::::::::

Fortunately, there are some solid networking examples on the git repository.

git clone git://git.rtems.org/network-demo network-demo

cd examples-v2
export RTEMS_MAKEFILE_PATH=~/development/rtems/4.11/arm-rtems4.11/raspberrypi/
make

http demo has an error

init.c: In function 'Init':
init.c:176:38: error: assignment of member 'login_check' in read-only object
   rtems_global_shell_env.login_check = rtems_shell_login_check;

telnetd has an error 

Let's first trace the simplest example = netdemoThere are two .c files in the folder: init.c and test.c
According to the README:

Once this program is running on the target machine, you can test
the network code by:

 Typing commands at the target console:
    - show network statistics
    - transmit TCP packets
    - transmit UDP packets
    Run `telnet target_machine 24742' on another machines.
 Everything you type should be echoed back and noted on
 the target console.
 You can run more than one telnet session at once.
 You can use port number 24743 as well.
