req-c7de08ad-67af-4e9f-91aa-37bc0ec08deb None None] Bridge br-ex for
physical network public does not exist. Agent terminated!

This seems to only show up in the tempest-slow* jobs on stable branches
for some reason:

%22screen-neutron-agent.txt%5C%22&from=7d

It also appears that this started around June 21.

The tempest-slow job runs slow scenario tests that other jobs like
tempest-full won't run, e.g.:

TestNetworkAdvancedServerOps.test_server_connectivity_cold_migration
TestNetworkAdvancedServerOps.test_server_connectivity_live_migration
TestNetworkAdvancedServerOps.test_server_connectivity_resize
