We are using Openvswitch networking and we have a physical 1G management
network and two 10G physical links bonded. The physical interfaces show a
state of UP when doing "ip a".

However for the OVS bond, bridges and internal ports we get a state of"
UNKNOWN". Is this expected?

Everything else is essentially working OK - The GUI marks the bond, bridge
and internal ports as active and traffic is working as expected, but I
don't know why the state of these is not UP?

An example of an internal port OVS Configuration in /etc/network/interfaces
(as setup by the GUI):

allow-vmbr1 vlan233
iface vlan233 inet static
ovs_type OVSIntPort
ovs_bridge vmbr1
ovs_options tag=233

and ip a output:

14: vlan233: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
*UNKNOWN* group default qlen 1000
    link/ether e2:53:9f:28:cb:2b brd ff:ff:ff:ff:ff:ff
    inet brd scope global vlan233
      valid_lft forever preferred_lft forever
    inet6 fe80::e053:9fff:fe28:cb2b/64 scope link
      valid_lft forever preferred_lft forever

The version we're running is detailed below. We rolled back the kernel as
we were having stability problems with 4.15.8 on our hardware (HP Proliant
