[Openstack] Writing an l3 agent

Hi all

I'm trying to write a customized l3 agent for my infrastructure and I need
some help on it.
The "/etc/neutron/l3_agent.ini" file gives me some hints but I'd like to
clarify them:

1) l3_agent_manager = neutron.agent.l3_agent.L3NATAgentWithStateReport

As its name implies, is it the agent for every l3 agent? Should it change
somehow depending on my l3 device?

2) interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

Is this the one I should actually change? I believe that nothing should
change in terms of instructions in and out openstack - only the real
commands to that specific l3 device shall change and they shall be
irrelevant for Openstack.

Thanks for any support on this.
