Description Gris Ge 2023-03-28 09:09:15 UTC 
Description of problem:

Give a dummy interface created by ip command with two ip addresses
When user modified the in-memory dummy connection of NetworkManager and run reapply
Then user are expecting IP address of dummy interface been preserved in NetworkManager as persistent configuration.

In nmstate state CI we noticed the IP address might(10% chance) got purged after the reapply action.

Version-Release number of selected component (if applicable):
NetworkManager-1.43.4-32057.copr.0a02995175.el8.x86_64

How reproducible:
10%

Steps to Reproduce:
1. git clone https://github.com/nmstate/nmstate.git
2. sudo dnf install python3-pytest nmstate -y
3. git checkout nmstate-1.4
4. sudo dnf install `./packaging/make_rpm.sh` -y
5. cd nmstate/tests/integration; 
6. sudo pytest-3 -vvv -k test_perserve_ip_order_of_external_managed_nic
7. Retry above command till it fail manually or using a `for` look.

Actual results:

Test case fail complaining about index error

Expected results:

No failure

Additional info:

I tried 100 times on NetworkManager-1.40.16-1.el8.x86_64 , no failure.

I tried 100 times the same version on RHEL 9.2, no failure(but nmstate is different there).
