I think we should use a newer OVS version that for the functional and fullstack
jobs at the very least. This will enable us to test the OVS firewall
working on, as well as the OVS ARP responder (Which was merged a long time
ago, but lacks proper testing because it needs OVS 2.1+ and we gate
using OVS 2.0).
So, that's the problem. How we solve it is another manner - I was
under the impression
that compiling it is our only option. Right now OVN are compiling
master, I think we
should avoid that and compile a specific git hash instead so the gate
won't break every
time OVS breaks. Then, when OVS branch out 2.5, we can 'pin' on that.
At that point
we could perhaps switch to a packaged OVS off some sort of experimental repo.
