Neutron plugin specific files
Neutron plugins require plugin specific behavior.
The files under the directory, lib/neutron_plugins/, will be used
when their service is enabled.
Each plugin has lib/neutron_plugins/$Q_PLUGIN and define the following
functions.
Plugin specific configuration variables should be in this file.
- filename:
$Q_PLUGIN- The corresponding file name MUST be the same to plugin name
$Q_PLUGIN. Plugin specific configuration variables should be in this file.
- The corresponding file name MUST be the same to plugin name
functions
lib/neutron-legacy calls the following functions when the $Q_PLUGIN is enabled
