I didn't see how could I adjust this to my configuration, but I had some dayjob
tasks, too ...

Great job, that's almost 50% of them!

I have applied them.

BTW, after running the full net/forwarding test suite, "ip link show"
looks like this:

This is kinda awkward, because I have to reboot the machine for the next run, each time.

I am in no condition to try to figure out which tests leaked links.

I will leave the machine on in case you need additional diagnostics.

Thanks.

Kind regards,
