I just noticed that the patch was marked as Related not Resolves for the bug. Moving back to ON_DEV and asking the owner to comment.
It was a mistake. It completely resolves this bug, so it should have been "Resolves" and "not Related".
The fix wee provided with openstack-neutron-10.0.0-13.el7ost is causing some other issue, so we will revert it and provide alternate fix u/s https://review.openstack.org/#/c/454832/ Please see below comments https://bugzilla.redhat.com/show_bug.cgi?id=1431026#c22 https://bugzilla.redhat.com/show_bug.cgi?id=1431026#c26
