+// Module Name:
+// CompletionFunctions_BasicPacketInjectionCallouts.cpp
+//
+// Abstract:
+// This module contains WFP Completion functions for injecting packets back into the data path
+// using the clone / block / inject method for modified NBLs.
+//
+// Naming Convention:
+//
+// <Module><Scenario>
+//
+// i.e.
+// CompleteBasicPacketModification
+//
+// <Module>
+// Complete - Function is an FWPS_INJECT_COMPLETE function.
+// <Scenario>
+// BasicPacketModification - Function demonstrates the clone / block / inject
+// model for modified NBLs.
+//
+// <Object><Action>
+//
+// i.e.
+// BasicPacketModificationCompletionDataDestroy
+//
+// <Object>
+// {
+// BasicPacketModificationCompletionData - pertains to
+// BASIC_PACKET_MODIFICATION_COMPLETION_DATA.
+// }
+// <Action>
+// Destroy - Cleans up and frees all memory in the object.
+//
+// Private Functions:
+// BasicPacketModificationCompletionDataDestroy(),
+//
+// Public Functions:
+// CompleteBasicPacketModification(),
+//
+// Author:
+// Dusty Harper (DHarper)
+//
+// Revision History:
+//
+// [ Month ][Day] [Year] - [Revision]-[ Comments ]
+// May 01, 2010 - 1.0 - Creation
+// December 13, 2013 - 1.1 - Enhance function declaration for IntelliSense and
+// enhance traces.
