    11 // Tier Manager

    12 //   (management plane)

    13 //

    14 //

    15 //  This is a 3-plane comms layer implementation example, which has been customised to be a test layer which gobbles and releases ESOCK MBUFs.

    16 //  The MBuf gobbling functionality can be disabled by undefining the macro SYMBIAN_COMMSFW_MBUF_GOBBLER which is specified in mbufgobblerproviders.mmp.

    17 //  When SYMBIAN_COMMSFW_MBUF_GOBBLER is undefined, the source code specified by mbufgobblerproviders.mmp becomes a pass through layer i.e. it passes the data

    18 //  through to the layer above or below without altering it. This makes it useful as a starting point for implementing your own layers / providers;

    19 //  useful documentation on how to customise your own passthrough layer can be found in ..\docs\MbufGobblerLayer.doc
