Supervisor create new connection interface when modified

[warshoot3r]

Describe the issue you are experiencing

If you use are using VLAN. This is not affected if you are using ethernet only or Wifi.

Few issues happening:
Connection name is incorrect. It displays "Supervisor eth0.30.30" rather
than it should be "Supervisor eth0.30".

The new UUID is being generated every time when you make a change on the vlan networks.

Supervisor creates a new connection in NetworkManager ending up with lots of duplicate connections. But they are not connected so it it not major issue.

What type of installation are you running?

Home Assistant Supervised

Which operating system are you running on?

Other (e.g., Raspbian/Raspberry Pi OS/Fedora)

Steps to reproduce the issue

1. SSH to host
2. Create VLAN with "ha network vlan eth0 20"
3. Run "ha network reload" so that vlan is visible in Network Tab.
4. http://:8123/config/network. Set it to disabled
5. http://:8123/config/network. Set it to Enabled
6. run "nmcli con" on the host. Supervisor creates another connection everytime it is modified
   ...

Anything in the Supervisor logs that might be useful for us?

I'd like to confirm that I can also repro this bug with vlans that were generated via nmcli. Enabling/disabling, or even turning ipv4/ipv6 on or off in the system UIs creates duplicated networks.

I'm experiencing this too. It would be helpful to resolve this as it makes it hard to automate management of the network interfaces.

@Particpant the naming fix is now on the stable channel. Can you check if this resolves the issue for you?

[Particpant]

Will do! Might be a day or so.

[Particpant]

Had some unexpected delays, still intending to verify the fix as soon as I can.
