Comment 2 for bug 1737892

I was checking few more case with such error. It looks that it's common issue that port is deleted from OVS (so vm.destroy() is called) before it is updated to mark as ACTIVE by L2 agent. For example:
- vm.destroy at 5:10:01.190: http://logs.openstack.org/81/468281/46/check/legacy-neutron-dsvm-fullstack/7aca78e/logs/dsvm-fullstack-logs/TestBwLimitQoSOvs.test_bw_limit_qos_port_removed_ingress,openflow-native_.txt.gz#_2017-12-19_05_10_01_190
- port updated as ACTIVE at 05:10:02.494: http://logs.openstack.org/81/468281/46/check/legacy-neutron-dsvm-fullstack/7aca78e/logs/dsvm-fullstack-logs/TestBwLimitQoSOvs.test_bw_limit_qos_port_removed_ingress,openflow-native_/neutron-openvswitch-agent--2017-12-19--05-09-41-666635.txt.gz
