Should I open a bug report or is it something I'm doing wrong? Lookiing
at the code, I see recent changes were made, which maybe introduced a
bug, in which case I'd be happy to help.

About the setup:

neutron with OVN agents, version 18.1.1.dev7, deployed with
kolla-ansible, nothing especially fancy.

Thanks in advance,
