network configuration setup - dhcp

Mon Apr 19 19:09:39 BST 2021

Hello Ahmad,

Yes, it would be very helpful and straightforward for future users to
set up DHCP networking.
Sure, I will submit a patch to add it in Documentation.

planning to include this as an example under the link:
https://www.barebox.org/doc/latest/user/networking.html#lowlevel-network-device-configuration
as 1.3.1.1. or if you want in other places then please let me know.

Thank you

Kind regards,
Neeraj
