求助！！！分析的数据包ip地址错误

各位：我是一个新手，在作驱动时从底层得到的数据报地址和我要分析的值不一致。
我的PtReceive函数如下：
PtReceive(
IN NDIS_HANDLE ProtocolBindingContext,
IN NDIS_HANDLE MacReceiveContext,
IN PVOID HeaderBuffer, // 包头
IN UINT HeaderBufferSize, // 包头大小，以太网环境下为14
IN PVOID LookAheadBuffer, // 前视缓冲
IN UINT LookAheadBufferSize, //
IN UINT PacketSize // 数据包总大小(不包括包头)
)
{
PADAPT OutAdapt, pAdapt =(PADAPT)ProtocolBindingContext;
PNDIS_PACKET MyPacket, Packet, MyPacket1;
NDIS_STATUS Status = NDIS_STATUS_SUCCESS;

PNDIS_BUFFER pPacketBuffer, pBakBuffer;
PUCHAR pPacketContent, pBakContent;
UINT PacketLen;

UINT OffsetSize;
UINT BytesTransferred;

PRSVD Rsvd = NULL;
PVOID MediaSpecificInfo = NULL;
ULONG MediaSpecificSize= 0;

DBGPRINT((\"In PtReceive\\n\"));

if(!pAdapt->MiniportHandle)
{
Status = NDIS_STATUS_FAILURE;
}
else do
{
// We should not be getting Receives on a Secondary, this is just specific to our LBFO driver
if(pAdapt->isSecondary)
{
DbgPrint(\"PASSTHRU GETTING RECIEVES ON SECONDARY\\n\");
ASSERT(0);
}
if(FALSE){}
else if(PacketSize <= LookAheadBufferSize)  // 如果 LookAheadBuffer 中包含了全部数据
{
// 分配内存
Status = NdisAllocateMemory(&pPacketContent, BUFFER_SIZE, 0, HighestAcceptableMax);
if(Status != NDIS_STATUS_SUCCESS)
{
DbgPrint(\"PTReceive:NdisAllocateMemory Failed\\n\");
return(NDIS_STATUS_NOT_ACCEPTED);
}
if(pPacketContent == NULL)
{
DbgPrint(\"PTReceive:pPacketContent==NULL\\n\");
return(NDIS_STATUS_NOT_ACCEPTED);
}
// 将包头和 LookAheadBuffer 复制到新分配的内存中
NdisZeroMemory(pPacketContent, BUFFER_SIZE);
NdisMoveMemory(pPacketContent, HeaderBuffer, HeaderBufferSize);
NdisMoveMemory(pPacketContent+ HeaderBufferSize, LookAheadBuffer, LookAheadBufferSize);
PacketLen = PacketSize+HeaderBufferSize;

if(Monitor_flag)
{
if(Check_Packet((char*)pPacketContent))
{
return NDIS_STATUS_NOT_ACCEPTED;
}
}
else {}

// 在包池中分配包描述符
NdisDprAllocatePacket(&Status, &MyPacket, pAdapt->RecvPacketPoolHandle);

if(Status == NDIS_STATUS_SUCCESS)
{
// 在缓冲池中分配缓冲描述符，将包描述符与缓冲描述符关联。
NdisAllocateBuffer(&Status, &pPacketBuffer, pAdapt->RecvBufferPoolHandle, pPacketContent, PacketLen);
NdisChainBufferAtFront(MyPacket, pPacketBuffer);

MyPacket->Private.Head->Next = NULL;
MyPacket->Private.Tail = NULL;
Rsvd=(PRSVD)(MyPacket->MiniportReserved);
Rsvd->OriginalPkt = NULL;
NDIS_SET_PACKET_HEADER_SIZE(MyPacket, HeaderBufferSize);

// 向上层协议驱动指示数据包，防真网卡行为。
NdisMIndicateReceivePacket(pAdapt->MiniportHandle, &MyPacket, 1);
if(NDIS_GET_PACKET_STATUS(MyPacket) != NDIS_STATUS_PENDING)
{
DBGPRINT((\"In PtReceive And Free Memory\\n\"));
NdisFreeBuffer(pPacketBuffer);
NdisFreeMemory(pPacketContent, BUFFER_SIZE, 0);
NdisDprFreePacket(MyPacket);
}
}
break;
}
else // 如果 LookAheadBuffer 中没有包含全部数据
{
// 分配内存 pPacketContent，存放要传输的除 LookAheadBuffer 之外的数据。
Status = NdisAllocateMemory(&pPacketContent, BUFFER_SIZE, 0, HighestAcceptableMax);
if(Status != NDIS_STATUS_SUCCESS)
{
DbgPrint(\"PtReceive:NdisAllocateMemory Failed.\\n\");
return(NDIS_STATUS_NOT_ACCEPTED);
}

// 分配内存 pBakContent，存放HeaderBuffer + LookAheadBuffer。
Status = NdisAllocateMemory(&pBakContent, BUFFER_SIZE, 0, HighestAcceptableMax);
if(Status != NDIS_STATUS_SUCCESS)
{
DbgPrint(\"PtReceive:NdisAllocateMemory Failed.\\n\");
return(NDIS_STATUS_NOT_ACCEPTED);
}
if(pBakContent == NULL)
{
DbgPrint(\"PTReceive:pPacketContent==NULL\\n\");
return(NDIS_STATUS_NOT_ACCEPTED);
}
// 将 HeaderBuffer + LookAheadBuffer 复制到 pBakContent 指向的内存中。
NdisZeroMemory(pBakContent, BUFFER_SIZE);
NdisMoveMemory(pBakContent, HeaderBuffer, HeaderBufferSize);
NdisMoveMemory(pBakContent+HeaderBufferSize, LookAheadBuffer, LookAheadBufferSize);

PacketLen = HeaderBufferSize + PacketSize;

// 为要传输的除 LookAheadBuffer 之外的数据分配缓冲描述符（该缓冲描述符与 pPacketContent 指向的内存关联）。
NdisAllocateBuffer(&Status, &pPacketBuffer, pAdapt->RecvBufferPoolHandle, pPacketContent, PacketSize-LookAheadBufferSize);
// 关联包描述符 MyPacket 与缓冲描述符 pPacketBuffer。
NdisChainBufferAtFront(MyPacket, pPacketBuffer);
MyPacket->Private.Head->Next=NULL;
MyPacket->Private.Tail=NULL;

OffsetSize = HeaderBufferSize + LookAheadBufferSize;

// 分配包描述符 MyPacket1。
NdisDprAllocatePacket(&Status, &MyPacket1, pAdapt->RecvPacketPoolHandle);
// 分配缓冲描述符 pBakBuffer，与 pBakContent 指向的内存关联。
NdisAllocateBuffer(&Status, &pBakBuffer, pAdapt->RecvBufferPoolHandle, pBakContent, OffsetSize);
// 关联包描述符 MyPacket1 与缓冲描述符 pBakBuffer。
NdisChainBufferAtFront(MyPacket1, pBakBuffer);

Rsvd = (PRSVD)(MyPacket->MiniportReserved);
Rsvd->OriginalPkt = (PNDIS_PACKET)MyPacket1;

NDIS_SET_PACKET_HEADER_SIZE(MyPacket, HeaderBufferSize);

// 取得 LookAheadBuffer 之后的数据
NdisTransferData(&Status,
pAdapt->BindingHandle,
MacReceiveContext,
LookAheadBufferSize, // 数据起始地址
PacketSize-LookAheadBufferSize, // 字节数
MyPacket,
&BytesTransferred);

if(Status != NDIS_STATUS_PENDING)
{
PtTransferDataComplete((NDIS_HANDLE)pAdapt, MyPacket, Status, BytesTransferred);
}
break;
}

pAdapt->IndicateRcvComplete = TRUE;

} while(FALSE);

return Status;
}

我想把得到的pPacketContent上传到应用程序，可得到的数据包很怪异，分析的数据包不正确！
急求正确解决方法！

怎么个奇怪法，贴出来看看。
