Debug Wrapper

The debug version of the wrapper allows developers to
1. turn on/off error checking
2. control level of tracing.  There are currently 2 levels of tracing:
Level 2 tracing turns on tracing on all wrapper functions; while level
1 tracing turns on tracing only on the more interesting functions.
Level 1 and 2 functions are enumerated below:


Level 1 Tracing enables tracing on the following functions:

        NdisInitializePacketPool
        NdisTerminatePacketPool

        NdisRegisterProtocol
        NdisDeregisterProtocol

        NdisOpenAdapter
        NdisCloseAdapter
        FinishOpen

        KillOpenAndNotifyProtocol
        KillOpen

        NdisInitializeWrapper
        NdisTerminateWrapper

        NdisRegisterMac
        NdisDeregisterMac
        DeQueueAdapterOnMac
        QueueAdapterOnMac

        QueueOpenOnProtocol
        DeQueueOpenOnProtocol
        NdisRegisterAdapter
        NdisDeregisterAdapter
        KillAdapter
        QueueAdapterOnAdapter
        DeQueueAdapterOnAdapter
        NdisSetPacketFilter
        NdisAddMulticastAddress
        NdisDeleteMulticastAddress
        NdisSend
        NdisTransferData
        NdisQueryInformation
        NdisSetInformation
        NdisReset
        NdisTest
        NdisCompleteRequest
        NdisCompleteSend
        NdisCompleteTransferData
        NdisIndicateStatus
        NdisIndicateStatusComplete


Level 2 tracing enables tracing the functions listedbelow in addition
to all Level 1 functions:

        NdisQueryBuffer
        NdisAllocatePacket
        NdisDeallocatePacket
        NdisReinitializePacket
        NdisChainBufferAtFront
        NdisChainBufferAtBack
        NdisUnchainBufferAtFront
        NdisUnchainBufferAtBack
        NdisQueryPacket
        NdisGetNextBuffer
        ReferenceRef
        DereferenceRef
        InitializeRef
        CloseRef
        ReferenceProtocol
        DereferenceProtocol
        NdisSuccessIrplHandler
        ReferencMac
        ReferenceAdapter
        DereferenceAdapter

        NdisIndicateReceive
        NdisIndicateReceiveComplete



Turning on/off error checking

Error checking may be turned on/off during run-time by changing the
value of the flag  NdisChkErrorFlag.  A zero value turns off error
checking and a non-zero value turn it on.  This flag is turned on
by default.


Controlling level of messages

Message level may by specified by changing the NdisMsgLevel variable.

        Value of NdisMsgLevel          Meaning
        0x000                          Turn off all messages
        0x001                          Turn on tracing on Level 1 functions
        0x002                          Turn on all tracing

NdisMsgLevel is set to 0 by default



The debug code will be included only if the NDISDBG flag is turned on (== 1).

If you do change this flag, be sure to delete (1) all nbf .obj files,
(2) ntos\dd\init\obj\i386\ddinit.obj, (3) ntos\init\obj\i386\init.obj, and
(4) recompile everything under ndis, since this flag will change a lot
of goings on inside ndis.h
