# functions - functions specific to neutron
# Dependencies:
# ``functions`` file
# ``DEST`` must be defined
# ``STACK_USER`` must be defined
# ``stack.sh`` calls the entry points in this order:
#
# - install_neutron_agent_packages
# - install_neutronclient
# - install_neutron
# - install_neutron_third_party
# - configure_neutron
# - init_neutron
# - configure_neutron_third_party
# - init_neutron_third_party
# - start_neutron_third_party
# - create_nova_conf_neutron
# - configure_neutron_after_post_config
# - start_neutron_service_and_check
# - check_neutron_third_party_integration
# - start_neutron_agents
# - create_neutron_initial_network
#
# ``unstack.sh`` calls the entry points in this order:
#
# - stop_neutron
# - stop_neutron_third_party
# - cleanup_neutron
# Functions in lib/neutron are classified into the following categories:
#
# - entry points (called from stack.sh or unstack.sh)
# - internal functions
# - neutron exercises
# - 3rd party programs
# Neutron Networking
# ------------------
# Make sure that neutron is enabled in ``ENABLED_SERVICES``. If you want
# to run Neutron on this host, make sure that q-svc is also in
# ``ENABLED_SERVICES``.
#
# See "Neutron Network Configuration" below for additional variables
# that must be set in localrc for connectivity across hosts with
# Neutron.
#
# With Neutron networking the NETWORK_MANAGER variable is ignored.
