      Given a system administrator has already created a bridge using Nmstate and aims to create a new bond to attach to this bridge, 

      When they apply a new configuration specifying both the existing bridge and the new bond setup to be created and linked to the bridge,

      Then, Nmstate should successfully create and attach the bond to the bridge without generating an error.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • The integration tests are written and pass 
      • The fix is part of a downstream build attached to an errata

      What were you trying to do that didn't work?

      I've created a bridge(BR-DHCP2) with nmstate, after that I want to create a bond(bond0_p) attaching to the bridge, when I also list the bridge in `interfaces`, it failed.

      3 conditions to reproduce:

      1. The controller(BR-DHCP2) already exists
      2. The controller is listed under `interfaces` key in the desired state, and it doesn't mention `port`(hence nmstaet shouldn't touch `port` part)
      3. The subordinate(bond0_p) doesn't exist before, to be created in the desired state

      The error is same with https://issues.redhat.com/browse/RHEL-1414 but the reproducer is different.

      Please provide the package NVR for which bug is seen:

      nmstate-2.2.27-1.el9.x86_64
      nispor-1.2.14-1.el9.x86_64
      NetworkManager-1.47.2-1.el9.x86_64

      How reproducible:

      100%

      Steps to reproduce

      echo "
interfaces:
- name: BR-DHCP2
  type: linux-bridge
  state: up
- name: bond0_p
  type: bond
  controller: BR-DHCP2
  state: up
  mtu: 9000
  link-aggregation:
    mode: 802.3ad" | nmstatectl apply # <----------------- pass when both didn't exist before 

echo "
interfaces:
- name: bond0_p
  type: bond
  state: absent" | nmstatectl apply

echo "
interfaces:
- name: BR-DHCP2
  type: linux-bridge
  state: up
- name: bond0_p
  type: bond
  controller: BR-DHCP2
  state: up
  mtu: 9000
  link-aggregation:
    mode: 802.3ad" | nmstatectl apply # <----------------- FAIL: BR-DHCP2 exists + creating bond0_p

echo "
interfaces:
- name: bond0_p
  type: bond
  controller: BR-DHCP2
  state: up
  mtu: 9000
  link-aggregation:
    mode: 802.3ad" | nmstatectl apply # <----------------- pass when BR-DHCP2 is not listed in `interfaces`

      Expected results

      Pass

      Actual results

      NmstateError: InvalidArgument: Interface bond0_p has controller BR-DHCP2 but not listed in port list of controller interface
