Yeah, the docs is now kind of obvious.

nit: Maybe blank line here (it's own paragraph). But even this is going to lead
to duplicity (functionality described in both places).

> +Network stress tests and environment parameters are defined in
These variables are also for other network tests than just stress tests.

The above is ok, but I would just point:

Network tests are documented in :master:`testcases/network/README.md`.
and delete the rest of the docs below ...

... because this Single-host and Two-host related sections is a duplicity of
testcases/network/README.md. I'm ok to move testcases/network/README.md to
readthedocs, but it should not be on 2 places.  I recently spent time to remove
doc duplicity, because sooner or later one of them gets outdated, please don't
introduce it again.

The other unrelated changes are ok (feel free to add my RBT for them if in a
separate commit).

Kind regards,
Petr
