Contribution description

Adds support for net_tools module into shell-extended module

Testing procedure

Go to examples/shell_extended and add the next line:

USEMODULE += net_tools

A good place for it could be just under USEMODULE += uniqueid, after it save changes, build and flash as usual:

make flash term

Once the shell is displayed, type help and push return or type one of the available commands for net-tools or uniqueid

I added some new changes in net_tools shell_extended commands, this will provides the functionalities to run all features as setting ipv6 by uniqueid. You can provides an ipv6 address using the generic input of ipv6. e.g: 2001:db8::/64.

Testing procedure.

• use the shell_extended_example:

make -C examples/shell_extended flash term

commands instructions:

if 4 add ipuid 2001:db8::/64 static

if --> command net_tool
4 --> interface id (Depends of your interface device).
add --> option to add an ipv6 addr (For this moments).
ipuid --> Additional and Exclusive option to generate and set a ipv6 address via `uniqueid` module.
2001:db8::/64 --> ipv6 address and network prefix. *note*: Always be predefined to get a random or static pv6 from a header. Remember add its prefix length.
static -> its the uniqueid ipv6 generation mode.

For me this looks good, but i prefer as own @luisan00, you give me your opinion about these features and commands.

what do you think about other command (without args) like:

• if : show pretty printed interfaces and stats
  or (with argument):
• if show: pretty print all interfaces and stats.
• if show [iface]: for example if show 4, should print interface 4 and stats
