Something I have gathered reading through code if it helps, ip_pipeline is
designed such that user side cli (_fe) runs in master pipeline and sends
conf requests to various other packet processing pipelines (_be) which
handle such requests at intervals. These can run on same or different
threads(cores) as per conf, no locking requirement as table-updation &
table-reading (packet processing) always happens in same pipeline so always
same thread. Master pipeline can be configured to run on a separate core &
it should be the case, but table updation happens in pipeline thread only
at lower priority.
