求助：passthru中的PtReceive是否多收了？

NDIS_STATUS PtReceive(..........)
{
PADAPT pAdapt =(PADAPT)ProtocolBindingContext;
PNDIS_PACKET MyPacket, Packet;
NDIS_STATUS Status = NDIS_STATUS_SUCCESS;

if(!pAdapt->MiniportHandle)
{
Status = NDIS_STATUS_FAILURE;
}
else do
{
if(pAdapt->isSecondary)
{
DBGPRINT(\"PASSTHRU GETTING RECIEVES ON SECONDARY\\n\");
ASSERT(0);
}

Packet = NdisGetReceivedPacket(pAdapt->BindingHandle, MacReceiveContext);
if(Packet != NULL)
{
NdisDprAllocatePacket(&Status,
 &MyPacket,
 pAdapt->RecvPacketPoolHandle);

if(Status == NDIS_STATUS_SUCCESS)
{
 MyPacket->Private.Head = Packet->Private.Head;
 MyPacket->Private.Tail = Packet->Private.Tail;

 NDIS_SET_ORIGINAL_PACKET(MyPacket, NDIS_GET_ORIGINAL_PACKET(Packet));
 NDIS_SET_PACKET_HEADER_SIZE(MyPacket, HeaderBufferSize);

 NdisGetPacketFlags(MyPacket) = NdisGetPacketFlags(Packet);

 NDIS_SET_PACKET_STATUS(MyPacket, NDIS_STATUS_RESOURCES);

 NdisMIndicateReceivePacket(pAdapt->MiniportHandle, &MyPacket, 1);

 ASSERT(NDIS_GET_PACKET_STATUS(MyPacket) == NDIS_STATUS_RESOURCES);
 NdisDprFreePacket(MyPacket);
 break;
}
}

pAdapt->IndicateRcvComplete = TRUE;
switch(pAdapt->Medium)
{
 case NdisMedium802_3:
NdisMEthIndicateReceive(pAdapt->MiniportHandle,
MacReceiveContext,
HeaderBuffer,
HeaderBufferSize,
LookAheadBuffer,
LookAheadBufferSize,
PacketSize);
break;

 case NdisMedium802_5:
NdisMTrIndicateReceive(pAdapt->MiniportHandle,
MacReceiveContext,
HeaderBuffer,
HeaderBufferSize,
LookAheadBuffer,
LookAheadBufferSize,
PacketSize);
break;

 case NdisMediumFddi:
NdisMFddiIndicateReceive(pAdapt->MiniportHandle,
 MacReceiveContext,
 HeaderBuffer,
 HeaderBufferSize,
 LookAheadBuffer,
 LookAheadBufferSize,
 PacketSize);
break;

 default:
ASSERT(0);
break;
}

} while(FALSE);

return Status;
}

当Packet = NdisGetReceivedPacket(pAdapt->BindingHandle, MacReceiveContext); ！= NULL  时，该列程是否对同一的数据内容同时执行了NdisMIndicateReceivePacket(pAdapt->MiniportHandle, &MyPacket, 1);与NdisMEthIndicateReceive(pAdapt->MiniportHandle, MacReceiveContext,
 HeaderBuffer,
HeaderBufferSize,
 LookAheadBuffer,
 LookAheadBufferSize,
 PacketSize);
是这样的吗？ 我认为这好象不妥。

小弟不才，望大虾指点。谢谢！！！
若顺便将解其中的缘由，我将以分相许。
 :D :D :D

没有呀！Packet = GetReceivedPacket（……）之后，如果Packet != NULL，则NdisMIndicateReceivePacket（……），后面有一个break语句跳出do……while啊，你没有看见berak么？

谢谢！
见笑了。。。。。。。一点小意思 :) :D
