    13 // Description:

    14 // MbufGobbler selector. Used by the Tier Manager to select the access point below

    15 //  (management plane)

    16 //

    17 //

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

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

    20 //  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

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

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

    23 //
