为什么得到的packet为空？

在imd中，用NdisGetReceivedPacket得到的packet为null，但是，我可以正常上网。我用softice监视了很长时间，得到的全是null。此问题，有人提出过。但是没有合适的答案。

[编辑 -  3/3/02 作者： KungFu]

老大，问题解决了吗？

我要等高人的指点！！！

?

诸位大虾，你们为什么不伸出你们的救援之手呀？

大侠们,再不指点两手,我都快给憋死了.xemexzj的代码我也试过,huyg的代码我也试过,都是不行!你们的代码在你们的机器上工作都正常吗?
pPrimaryAdapt问题解决了,你用的是2k上的sample.我用的是xp上的.现在我也用2k上的了.
我把代码贴出来,请帮忙分析一下.谢谢!
注释掉的是xemexzj和微软的源吗,别的是HUYG和微软的.

请问xemexzj，huyg，在PtTransferDataComplete例程里面
pAdapt = pAdapt->pPrimaryAdapt;
pPrimaryAdapt是怎么得到的？在北京吗？我请你吃饭！！！！

对于Packet==NULL我就是没有解决呀！否则也不用敬仰别人了！

老胡呀,诸位能决问题的大虾呀,你看看这个问题怎么解决...
代码就是上面老胡铁出来的那部分:
PtTransferDataComplete(...)
{
       ...
       Packet->Private.Tail=NULL;
       NDIS_SET_PACKET_HEADER_SIZE(Packet,14);
       NdisMIndicateReceivePacket(
                    pAdapt->MiniportHandle ,
                    &Packet,
                    1);
       ....
}
当执行NdisMIndicateReceivePacket时候,出现PageFault,你说该怎么办?
NdisMIndicateReceivePacket是不是就是执行((PNDIS_MINIPORT_BLOCK)(_H))->PacketIndicateHandler它呢?

请问版主,NdisMIndicateReceivePacket(...)中的Packet只能带一个buffer吗?

老大，不要拿兄弟们开涮好不好？如果我精于此道的话，我也就不问了！！唉，惨呀，这个如肉强食的世界！！！：（

这真是太有创意了，我简直受不了了。还有很多56k的moden
也用ndisxxxindicatepacket，那怎么办？

一旦加载这个驱动，page fault。还请hu大虾看看是怎么回事？谢谢！

的确如此，您上面贴出的code是放在ndisXXXindicatepacket后面呢还是前面？
这些新分配的资源怎样free呢？应该是在PtTransferDataComplete里吧？
其实也不是戴高帽，古语说达者为师！

忘掉那行ndisXXXindicatepacket吧。很简单，删掉它，以及那个
switch，因为我们不再需要它了。我们要对所有的medium做通用
处理，只需要用ndisindicatepacket。整个函数的结构如下：
if (ndisgetpacket!=null)
{
//第一种情况
ndisindicatepacket
}
else if (PacketSize <= LookAheadBufferSize)
{
//第二种情况

switch(medium)
{
case 802.3:
setpacketheadsize(14);
case fddi:
}
ndisindicatepacket
}
else
{
//第三种情况
case 802.3:

MPTransferData与在ptreceive里面调用NdisTransferData有关系吗？

huyg别见笑，这是我在PtTransferDataComplete里面做的工作。但是问题出在哪里呢？
