Supervisor forgets the default interface's static network addresses after router restart (but not always)

[lmagyar]

Describe the issue you are experiencing

After router restart, Supervisor API returns empty network interface address array.
The IPv4 address is static, no DHCP requested, though the router has DHCP server.
ha su reload doesn't help
ha su restart needed to get valid values back
And it doesn't happen all the time, "just" approx. 50% of the time.
Any add-on that uses these information, will malfunction.

~ # bashio::api.supervisor GET "/network/interface/default/info" false | jq -M
{
  "interface": "enu1u1",
  "type": "ethernet",
  "enabled": true,
  "connected": true,
  "primary": true,
  "mac": "B8:27:EB:2F:8F:FA",
  "ipv4": {
    "method": "static",
    "address": [],    <<<<<<<<<<<<<<<<<<<<<<<<<<< ?!?!?!?!?!?!
    "nameservers": [],
    "gateway": null,
    "ready": true
  },
  "ipv6": {
    "method": "disabled",
    "address": [],
    "nameservers": [],
    "gateway": null,
    "ready": true
  },
  "wifi": null,
  "vlan": null
}

And it has address, I'm accessing these info through a functioning interface...

$ ifconfig enu1u1

Which operating system are you running on?

Home Assistant Operating System

Steps to reproduce the issue

1. ha net info - OK
2. reboot router (Mikrotik)
3. ha net info - missing info

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

The supervisor log is not so intresting, I've merged the Network Manager's events from one of my add-on, plus the router's events with the Supervisor log.

Note: Router reboot started, router is down

I've made some tests:

• different routers: not relevant
• different OS-s: relevant! It seems that
  • rpi3-32 nearly always lose the static IP address when router restarted
  • rpi3-64 (original post above) a bit less often
  • rpi4-64 never lost the static IP when router restarted.

"Lost static IP" means: it works, but ha net info shows empty address lists.
