+// Declares MBuf logging
+// 
+//
+
+#ifndef MBUF_LOG
+#define MBUF_LOG
+
+#include "comms-infras/commsdebugutility.h" // for __FLOG*
+#include "cflog.h"
+__FLOG_STMT(_LIT8(KSubsysMBufMgr, "MBufMgr");) // subsystem name
+__FLOG_STMT(_LIT8(KComponentPerformance, "performance");)	// component name - used for any sub-optimal performance behaviuor
+
+// CDU and flogger have multiple conflicts (eg. KLogBufferSize), consequently theirs headers can not both be included at the same time
+// - eg. tcpip6 uses flogger & mbufs
+// - solutions/workarounds;
+//   1. __FLOG_STATIC* macros --> open & close the CDU for every logging statement
+//	    +ve - does not use __FLOG_DECLARATION_MEMBER in the class decleration (ie. typically public)
+//      -ve - very slow
+//   2. __CFLOG* macros --> uses __FLOG_DECLARATION_MEMBER stored within commsfw (requires a TLS lookup for every logging statement)
+//	    +ve - does not use __FLOG_DECLARATION_MEMBER in the class decleration (ie. typically public)
+//      -ve - slow, but not as slow as static
+//   3. __CFLOG* macros --> uses __FLOG_DECLARATION_MEMBER stored within class
+//	    +ve - fast, no TLS or open/close of CDU
+//      -ve - clashes arise when users of the class include the header file if they use flogger instead of CDU
+//   4. As per 3, except that __FLOG_DECLARATION_MEMBER is not used; TInt iFlogger added to classes & __logger__ defined (refer below)
+//	    +ve - no clashes for users that use flogger
+//      -ve - requires a redecleration of __logger__ --> ideally this could/should be made available by a CDU header file (but alas is not)
+#define __logger__ (reinterpret_cast<RFileLogger&>(iLogger))
