Title:
  [OVN] OVN fails to report to placement if other mech driver is
  configured

Status in neutron:
  Fix Released

Bug description:
  Bugzilla reference:
  https://bugzilla.redhat.com/show_bug.cgi?id=2103019

  NOTE: we don't catch this error in our CI because we don't test OVN
  with other mech drivers, for example SR-IOV. This is happening in
  versions prior to Zed (the bugzilla refers to Wallaby).

  Description of problem:
  OSP17 (Wallaby) environment with OVN+SRIOV configured

  sriov_agent.ini includes the following minimum BW configuration that should be reported to placement:
  [sriov_nic]                                                                                                                                                                                                                                   
  physical_device_mappings=datacentre:enp7s0f3,datacentre:enp5s0f0
  resource_provider_bandwidths=enp7s0f3:10000000:10000000,enp5s0f0:10000000:10000000
  resource_provider_hypervisors=enp7s0f3:computesriov-0.localdomain,enp5s0f0:computesriov-0.localdomain                                                                                                                                         

  placement section is correctly configured on neutron.conf:
  [placement]
  auth_url=http://10.20.1.65:5000
  username=nova
  password=D6BO88QBbKbEYI76XkNzX5W68
  project_domain_name=Default
  project_name=service
  user_domain_name=Default
  region_name=regionOne
  auth_type=password

  
  When the sriov-agent running in a compute node is restarted, it successfully generates the information that should be reported to placement:
