So from a user symptom / impact standpoint, when new instances are nova
booted, they are able to send DHCP DISCOVER packet through the
corresponding bridge, but return DHCP OFFER traffic never reaches the
new instance.
In all cases that I have seen, the neutron net, subnet, and port

I've spoken with upstream about this and the commit identified probably
resolves this issue (testing on our internal cloud appears to confirm
this with packages from ppa:james-page/openvswitch).
I've requested a new point release, however if that does not appear in a
reasonable period of time,
https://github.com/openvswitch/ovs/commit/dd2e44f835fac8c2df99f84c54250c3ca981f2f5
might be a potential fix
