Abstract:
|
|
|
|
This file contains the procedures that makeup most of the NDIS 4.0/5.0
|
|
Protocol interface. This interface is what NdisWan exposes to the
|
|
WAN Miniports below. NdisWan is not really a protocol and does not
|
|
do TDI, but is a shim that sits between the protocols and the
|
|
WAN Miniport drivers.
