Hi, I am setting up an openstack instance with kolla-ansible. And I've come into a bit of an 'question' with networking. I have 2 x Mellanox connectx6 with 2x25 ports. One is for openstack/ceph operations and the second is for tenant/provider network for VM-s.  After configuring `neutron_external_interface=bond1` I get this state -> 

```
9: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovs-system state UP group default qlen 1000
    link/ether 22:5e:58:0e:02:51 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::205e:58ff:fe0e:251/64 scope link 
       valid_lft forever preferred_lft forever
10: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 6e:ed:43:48:6b:a6 brd ff:ff:ff:ff:ff:ff
20: br-ex: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 3a:63:6f:e1:be:42 brd ff:ff:ff:ff:ff:ff
21: br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether fa:d4:ae:84:76:47 brd ff:ff:ff:ff:ff:ff
22: genev_sys_6081: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 65000 qdisc noqueue master ovs-system state UNKNOWN group default qlen 1000
    link/ether 5e:74:a9:98:10:8a brd ff:ff:ff:ff:ff:ff
    inet6 fe80::f836:ffff:feb4:cb38/64 scope link 
       valid_lft forever preferred_lft forever
```

I thought the br-ex and br-int were going to be bridge devices, currently `brctl show` doesn't show anything.

The bond is configured on a TRUNK port with all vlan-s allowed and from the switch side no vlan tagging is done, eg. it is not an access port where the vlan tagged is removed when moving from switch -> computer.

So what should I change about this setup for it to work?
