linux_bond member in a ovs_bridge does not support ovs_extra so:

ovs-vsctl set <port_name> <port_config>

cannot be provided.
This issue happens for both providers: ifcfg and nmstate.

Reproduction procedure
Loading a config like this:

network_config:
- type: ovs_bridge
  name: br0
  use_dhcp: false
  use_dhcpv6: false
  ovs_extra: 
  - "set bridge br0 stp_enable=true"
  - "set bridge br0 other_config:stp-priority=4096"
  - "set port bond0 other_config:stp-path-cost=2"
  members:
  - type: linux_bond
    name: bond0
    mtu: 9000
    bonding_options: "mode=active-backup"
    members:
    - type: interface
      name: nic5
      primary: true
  - type: vlan
    vlan_id: 137
    mtu: 9000
    device: bond0
    addresses:
    - ip_netmask: "172.31.0.101/24"

It raises an error like this:

2025-10-16 14:49:03.004 ERROR os_net_config.main ifcfg: Failed to configure network_config.

Because the set port bond0 other_config:stp-path-cost=2 is added to bridge configuration:

# This file is autogenerated by os-net-config
DEVICE=br0
ONBOOT=yes
HOTPLUG=no
NM_CONTROLLED=no
PEERDNS=no
DEVICETYPE=ovs
TYPE=OVSBridge
OVS_EXTRA="set bridge br0 other-config:mac-table-size=50000 -- set bridge br0 stp_enable=true -- set bridge br0 other_config:stp-priority=4096 -- set port bond0 other_config:stp-path-cost=2 -- set bridge br0 fail_mode=standalone -- del-controller br0 -- set bridge br0 fail_mode=standalone -- del-controller br0"

Providing ovs_extra in a linux_bond member raises this expected validation error (no supported by the schema):

2025-10-16 14:52:50.382 ERROR os_net_config.main Schema validation failed for network_config with error:

  -- items/oneOf/ovs_bridge/members/items/oneOf/linux_bond/additionalProperties: Additional properties are not allowed ('ovs_extra' was unexpected)

Expected behavior
Providing a config like this:

network_config:
- type: ovs_bridge
  name: br0
  use_dhcp: false
  use_dhcpv6: false
  ovs_extra:
  - "set bridge br0 stp_enable=true"
  - "set bridge br0 other_config:stp-priority=4096"
  members:
  - type: linux_bond
    name: bond0
    mtu: 9000
    bonding_options: "mode=active-backup"
    ovs_extra:
    - "set port bond0 other_config:stp-path-cost=10"
    members:
    - type: interface
      name: nic5
      primary: true
  - type: vlan
    vlan_id: 137
    mtu: 9000
    device: bond0
    addresses:
    - ip_netmask: "172.31.0.101/24"

It should generate a config like this:

[root@compute-1 ~]# # add OVS_EXTRA with set port bond0 other_config:stp-path-cost=10 to ifcfg-bond0
[root@compute-1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0 
# This file is autogenerated by os-net-config
DEVICE=bond0
ONBOOT=yes
HOTPLUG=no
NM_CONTROLLED=no
PEERDNS=no
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br0
MACADDR="f8:f2:1e:33:04:e2"
BONDING_OPTS="mode=active-backup"
MTU=9000
OVS_EXTRA="set port bond0 other_config:stp-path-cost=10"

# restart service
[root@compute-1 ~]# systemctl restart network

Resulting in a ovs-vsctl set <port_name> <port_config> effectively applied:

[root@compute-1 ~]# ovs-appctl stp/show
