Hi Sławek,

In general, all that should be needed to extend ML2 with new drivers is:

1) Add the new driver class(es)
2) Add the new driver entry points to neutron.ml2.type_drivers and/or
neutron.ml2.mechanism_drivers in setup.cfg.
3) When using the new drivers, list their entry points in type_drivers
and/or mechanism_drivers in the [ml2] section of
etc/neutron/plugins/ml2/ml2_conf.ini, and add any other needed
configuration for those drivers.

I think discussing the specifics of what you are trying to accomplish
with these new drivers on openstack-dev, at the upcoming design summit,
at the weekly ML2 IRC meeting, and/or in a blueprint, would pay off,
since adding new drivers may or may not be the best solution. Generally,
type drivers should correspond to specific virtual network segmentation
methods, or maybe to variations on the way those are managed (i.e.
tunnel endpoint management).

Hope this helps,

-Bob
