Comment 3 for bug 1774203

FYI, my workaround is the following:

```
    bridges:
        loop1:
            dhcp4: no
            dhcp6: no
            accept-ra: no
            interfaces: []
            addresses: ['A.B.C.D/32']
```

# ethtool -i loop1
driver: bridge
version: 2.3
firmware-version: N/A
expansion-rom-version:
bus-info: N/A
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
