====================
netdev doc de-FAQization

We have outgrown the FAQ format for our process doc.
I often find myself struggling to locate information in this doc,
because the questions do not serve well as section headers.
Reformat the document.

v2: update the headers
v1: https://lore.kernel.org/all/[email protected]/
