Subject: [RFC PATCH net-next 0/2] selftests/tc-testing: initial steps for parallel tdc

As the number of tdc tests is growing, so is our completion wall time.
One of the ideas to improve this is to run tests in parallel, as they
are self contained. Even though they will serialize over the rtnl lock,
we expect it to give a nice boost.

A first step is to make each test independent of each other by
localizing its resource usage. Today tdc shares everything, including
veth / dummy interfaces and netns. In patch 1 we make all of these
resources unique per test.

Patch 2 updates the tests to the new model, which also simplified some
definitions and made them more concise and clearer.
