* NDIS driver calls into several functions in the NDIS.SYS Windows

* by the NDIS subsystem. Using the PE loader, we can patch our own

* versions of the NDIS routines into a given Windows driver module and
|
|
* convince the driver that it is in fact running on Windows.
|
|
*
|
|
* We provide a table of all our implemented NDIS routines which is patched
|
|
* into the driver object code. All our exported routines must use the
|
|
* _stdcall calling convention, since that's what the Windows object code
