It's an example for how to use libnm and asynchronous API.
But it's also a script I will use to test activating many
profiles in parallel.
Also add a test script that creates many veth interfaces and connection
profiles. So now you can do:
sudo NUM_DEVS=100 contrib/scripts/test-create-many-device-setup.sh setup
./examples/python/gi/nm-up-many.py c-a{1..100}
and cleanup with
nmcli connection down c-a{1..100}
sudo contrib/scripts/test-create-many-device-setup.sh cleanup
Of course, be careful to do this on your production machine.
