Sorry I think I gave Gary some bad information here.

After digging into this more, the actually underlying issue that we hit is that the packaged 'distro' version of stable/liberty that was running with the vmware-nsx repo included this patch set which is not in upstream stable/liberty

https://github.com/openstack/neutron/commit/7267d75fdd3f90af759d71e9490cd41d41ba6d98<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_openstack_neutron_commit_7267d75fdd3f90af759d71e9490cd41d41ba6d98&d=CwMFaQ&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=VlZxHpZBmzzkWT5jqz9JYBk8YTeq9N3-diTlNj4GyNc&m=W892wB0u3s_K0vG45Yac48hZEChj_a0By3Wz56bodqo&s=KsyWOnTC6FV2c0x0IBbJo1Dg6D91uhYGNgqO4TMo5_k&e=>

That's what was causing the issue on our end.  All should be okay upstream. Sorry about the confusion.

Aaron

Would you mind sharing details about the breakage? It was assumed that the patch backported includes the relevant compatibility bits to avoid any breakage. If that’s not the case, we should definitely come up with a way to get existing drivers unbroken again.

It may be either revert, or a new patch that would accommodate for your broken driver. It depends on breakage details. So please share those.

Absolutely. The change was not expected to require any changes for 3party drivers. If it happened, that’s our fault, and maybe we should land something, or revert. We should not leave it broken for 3party drivers.
