[Option] Flow Control [Description] 
Enables or disables the flow control feature. When enabled, this feature works in conjunction with the Max Buffer Size setting to determine the maximum number of messages for sequence that can be stored at the endpoint awaiting delivery to the application. Messages may have to be withheld from the application if ordered delivery is required and some of their predecessors have not arrived. If the number of stored messages reaches the threshold specified in the Max Buffer Size setting, incoming messages belonging to the sequence are ignored.
