commit d0fa2c9ac50a783c410fab2df938974c4e829ffa Author: Yang JianFeng <yjf1970231...@gmail.com> Date: Sat Jun 2 05:10:59 2018 +0000 Don't skip DVR port while neutron-openvswitch-agent is restared. neutron-openvswitch-agent will refresh flows when it's restarted. But the port's binding status is not changed, update_port_postcommit will be skipped at function '_update_individual_port_db_status' in 'neutron/plugins/ml2/plugin.py', l2pop don't handle DVR ports, the fdb entries about DVR port will not be added. So, we can't skip DVR port at notify_l2pop_port_wiring when agent is restared.
