Using these tools allow developers to stop thinking about coding style 
and focus on more important matters :)

Both black and ruff have the same formatting rules and use a default 88 
line length limit. Which yields good results in most cases:

I would prefer if we kept the default settings without any 
customization. The DPDK code base is already allowed to go up to 100 
columns anyways.
