Comment 1 for bug 1905640

Sorry, correction. It results in two `name: br-NAME` bridges defined on after the other in `/etc/os-net-config/config.yaml`, not in OvS. The problem is that the second one doesn't get created in OvS.

So this output is from my config.yaml file:
```
- type: ovs_bridge
  name: br-tenant
  mtu: 9000
  dns_servers: ['8.8.8.8']
  use_dhcp: false
  addresses:
  - ip_netmask:
      172.16.0.120/24
  routes: []
  members:
  - type: interface
    name: nic5
    mtu: 9000
    use_dhcp: false
    primary: true
- type: ovs_bridge
  name: br-ex
  mtu: 9000
  dns_servers: ['8.8.8.8']
  use_dhcp: false
  addresses:
  - ip_netmask:
      172.20.10.23/16
  routes: [{'default': True, 'next_hop': '172.20.0.254'}]
```
