Hi,
Thanks for the quick fix, and sorry for the inconvenience. 
I pushed a similar patch for rally-openstack to remove linuxbridge from mechanism_driver list, as I see the neutron task no need for linuxbridge:

https://review.opendev.org/c/openstack/nova/+/848948 has now merged in nova and the
os-vif change have also merged

so the nova/os-vif check and gate pipelines should now be unblocked and its is ok to recheck (with a reason) if requried.
