In the code snippets you seem to always call NdisDprFreePacket() on the
just allocated packets.
You must not free such packets as long as they are in use by other
networking components. That is, when you pass a newly allocated packet
to either NdisMIndicateReceivePacket() or NdisSend(), you must wait
until that packet is returned to you via either MiniportReturnPacket()
or NdisMSendComplete(), respectively.
The only exceptions to this rule are:
1. ..if you set the packet's Status to NDIS_STATUS_RESOURCES before
indicating up the packet descriptor.
2. ..if NdisSend() returns anything else but NDIS_STATUS_PENDING.
Please see the DDK docs for details.
