Public bug reported:

Not sure if we make it intentionally, but exceptions in extension driver
is interceptered by extenstion manager.

https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/managers.py#L351

for examples, when a port creating,  if one of the ext drivers emit a
exception, the extension process could continue for the left ext
drivers. But it may cover some error in that problem driver.  Maybe that
driver emit the exception passively(because of error in code) or
intentionally(some kind of verification in ext driver itself).

maybe I understand it wrong.
