Subject: [PATCH net] selftests: add a tc matchall test case

This is a follow up of the commit 0db6f8befc32 ("net/sched: fix ->get
helper of the matchall cls").

To test it:
$ cd tools/testing/selftests/tc-testing
$ ln -s ../plugin-lib/nsPlugin.py plugins/20-nsPlugin.py
$ ./tdc.py -n -e 2638

I'm not sure to understand the goal of this series:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?h=45b3a3762721

But after it, tc selftests are not intuitive anymore. When naively running them
(./tdy.py), all fw filter tests fail. It's hard to understand that the problem
is that they require the 'nsPlugin' plugin to be enabled (by adding a symlink
*and* providing the '-n' option to tdc.py).

Brenda, why putting the netns code into a plugin that is disabled by default,
knowing that this code is mandatory to run the test?

Regards,
Nicolas
