The new framework allows to start specific types of LLC control flows, protects active flows and makes it possible to wait for flows to finish before starting a new flow. This mechanism is used for the LLC control layer to model flows like 'add link' or 'delete link' which need to send/receive several LLC messages and are not allowed to get interrupted by the wrong type of messages. 'Add link' or 'Delete link' messages arriving in the middle of a flow are delayed and processed when the current flow finished. Signed-off-by:
