in ML2 plugin and it should rebind ports after agent is back.

Title:
openvswitch-agent doesn't try to rebind "binding_failed" ports on
startup anymore
Status in neutron:
Fix Released
Bug description:
When ports are created while the openvswitch agent is they're ending
up with "binding:vif_type=binding_failed". In the past upon the next
start of the agent it picked up those ports and would retry to bind
them at least once.
However, currently that is not happening anymore. The agent just logs
a message about the port not being bound. This is from the ovs-agent's
log directly after startup (9cdbb5cb-6e93-4043-bca9-b063cd43626d being
the port id of the "binding_failed" port):
