First, if you don’t use FWaaS, then why have you installed neutron-fwaas  
package? Please remove it. Also, make sure that your l3_agent.ini does not  
contain any fwaas remnants (I suspect you may have [fwaas] enabled = True  
there). Finally, check that neutron-server does not attempt to load fwaas  
service plugin (you can check it in log messages from oslo.config that are  
dumped at the service startup, specifically, check service_plugins value).
