<div dir="ltr">Hi Eric,<div><br></div><div>Instead of the new patch you may consider reverting an old one:</div><div><a href="https://review.openstack.org/#/c/23160/">https://review.openstack.org/#/c/23160/</a><br></div><div>
<a href="https://bugs.launchpad.net/neutron/+bug/1124117">https://bugs.launchpad.net/neutron/+bug/1124117</a><br></div><div><br></div><div>IMHO there's some confusion in bug #1124117 and in the patch in review #23160 about how a noop driver is expected to work. I believe a noop driver should look like it is present (in the list of available extensions), but does nothing. The patch in review #23160 believes an other way and makes the noop driver look like as if it wasn't even present. Which may lead to your current bug.</div>
