Title:
  ovn load balancer health monitor cause mac address conflict

Status in neutron:
  Expired

Bug description:
  The ovn octavia provider has added the support for health monitor in a commit one year ago:
  https://opendev.org/openstack/ovn-octavia-provider/commit/8bbd8f1b62d7811433079bff8ce940fbdd041a0c

  It reuse the OVN distributed DHCP
  port(device_owner="network:distributed"), whose mac address is
  allocated by neutron, but in the ovn's implementation, the health
  monitor message will be sent from this ip with a different mac address
  obtained from NB_Global table in northbound db. This breaks the ARP
  protocol and metadata request to ovn metadata agent will timeout. A
  possible fix is to use a different neutron port for the health monitor
  purpose.
