Open Stack

hi,

please consider that maintaining drivers from one openstack version to
others is really hard when those drivers are out of the scope of
neutron developers/continuous Integration process. For instance, ML2
is currently refactored by this patch :

https://review.openstack.org/#/c/82945/

you will have to adapt your code permanently!

regards
