#
# Kuryr will call neutron extension API to verify if neutron support

# plugin. The process of devstack is:
# ...
# run_phase "stack" "post-config"
# ...
# start neutron-server
# ...
# run_phase "stack" "extra"
#
# If Kuryr start up in "post-config" phase, there is no way to make

# phase. Bug: https://bugs.launchpad.net/kuryr/+bug/1587522
