network driver->design guide->part 1 ,2.2.1

When a transport driver has a packet to transmit, it calls an NdisXxx function exported by the NDIS library. NDIS then passes the packet to the miniport by calling the appropriate MiniportXxx function exported by the miniport. The miniport driver then forwards the packet to the NIC for transmission by calling the appropriate NdisXxx functions。

最后一句，怎么还要调用NDISXXX函数呢？搞不懂！

NdisRawWritePortUchar

这种函数也可以算在NdisXXXX中啊
