Fix proposed to branch: master
Review: https://review.openstack.org/322490

[Ihar Hrachyshka (ihar-hrachyshka)]

I don't think the refactoring was supposed to change any behaviour. If it did, it was a bug in the refactoring patch.

Change abandoned by garyk (<email address hidden>) on branch: master
Review: https://review.openstack.org/322490
Reason: Turns out that this may be a specific plugin issue. Still not clear why the refactor broke us :).

This doesn't happen in the stantard ml2 plugin. It could be an implementation detail in the nsx plugin, from a change of behaviour in the internal apis may be (sorry for breaking you in that unexpected way :/ )

The tempest side patch was abandoned and Neutron team seems to get a consensus to fix this problem on Neutron side. So I'd like to mark this as "Won't Fix" on Tempest side.
