Hi.


> I want to write a new neutron L2 plugin using ML2 framework, I noticed openvswitch and linxubridge have been ported into ML2 framework, but it seems many code is removed compared to standalone L2 plugin, I guess some code has been written into a common library. Now I want to write a L2 plugin to enable switch for a SR-IOV 10g NIC, I think I need to write as follows:

This requires to define how your plugin utilize network.
If multi tenant network is wanted, what/how technology will be used.
The common one is VLAN or tunneling(GRE, VXLAN).
This depends on what feature your NIC supports.

LOG.debug and debug middle ware.
If there are any other better way, I'd also like to know.

thanks,
