    Load Linux Bridge Trunk extension if service plugin configured
    
    Load the Linux Driver Trunk agent extension driver only if the service
    plugin is enabled. If the service plugin is not enabled, the agent
    extension will not subscribe to the port events.

Title:
  [LB] Linux Bridge agent always loads trunk extension, regardless of
  the loaded service plugins

Status in neutron:
  Fix Released

Bug description:
  Linux Bridge agent always loads trunk extension, regardless of the
  loaded service plugins. The trunk agent extension execute unnecessary
  operations that slows down the agent execution.

  For example:

  08-56-07-279444_log.txt

  A new port is added. The trunk agent extension receives those events a executes the port processing:
