I've submitted a devstack change to fix this, the review is listed below for those interested. I'm unclear how this was approved into Quantum given that it pretty much broke everyone using devstack with the OVS plugin, I would have expected a matching devstack patch to make devstack work as well. Regardless, the change to devstack is relatively minor, but will thus make devstack only work with the latest version of Quantum, given this config file change. Since I don't believe devstack works with older versions of anything, I believe this to be ok.

I believe that is because Quantum still only lists 1.1.0 as a
dependency: the gate uses trunk rather than the pip installed
dependencies, which means the gate couldn't detect this (assuming
1.1.1 does fix it).

FWIW we don't deploy via devstack, but the process is fairly similar:
grab trunk, install it with deps from pypi + packages for openvswitch
etc, then go : so while there weren't tests to trigger it, my concern
is that the gate setup wouldn't detect the problem *even with tests*,
because the problem is a requirement file that isn't being honoured
due to the gate setup.
