Description Gianluca Gabrielli 2023-06-08 06:49:36 UTC 
The service monitor MAC is exposed through the following flow:
ovn_lflow_add(lflows, od, S_SWITCH_IN_L2_LKUP, 110,
              "eth.dst == $svc_monitor_mac",
              "handle_svc_check(inport);");

This doesn't handle rate limit via CoPP. There is potential to
DoS ovn-controller even on deployments with CoPP enabled and configured
as all packets with this destination mac within the switch are sent directly to pinctrl thread in ovn-controller.
