====================
net: manually convert files to ReST format - part 1

There are very few documents upstream that aren't converted upstream.

This series convert part of the networking text files into ReST.
It is part of a bigger set of patches, which were split on parts,
in order to make reviewing task easier.

The full series (including those ones) are at:

And the documents, converted to HTML via the building system
are at:
