+//
+// Abstract:
+// This module contains WFP Completion functions for injecting packets back into the data path
+// using the clone / block / inject method.
+//
+// Naming Convention:
+//
+// <Module><Scenario>
+//
+// i.e.
+// CompleteBasicPacketInjection
+//
+// <Module>
+// Complete - Function is an FWPS_INJECT_COMPLETE function.
+// <Scenario>
+// BasicPacketInjection - Function demonstrates the clone / block / inject
+// model.
+//
+// <Object><Action>
+//
+// i.e.
+// BasicPacketInjectionCompletionDataDestroy
+//
+// <Object>
+// {
+// BasicPacketInjectionCompletionData - pertains to BASIC_PACKET_INJECTION_COMPLETION_DATA.
+// }
+// <Action>
+// Destroy - Cleans up and frees all memory in the object.
+//
+// Private Functions:
+// BasicPacketInjectionCompletionDataDestroy(),
+//
+// Public Functions:
+// CompleteBasicPacketInjection(),

+//
+// [ Month ][Day] [Year] - [Revision]-[ Comments ]
+// May 01, 2010 - 1.0 - Creation
+// December 13, 2013 - 1.1 - Enhance function declaration for IntelliSense, add
+// support for multiple injectors, and enhance traces.
