intermediate driver and driver I/O

I need to transfer data from user space to intermediate NDIS driver.
Is possible to do it with driver I/O ?
(with adding Dos symbolic link and registering
->MajorFunction[IRP_MJ_CREATE] = DriverDispatch....
->MajorFunction[IRP_MJ_WRITE] = DriverDispatch....
...
...

Or there is other prefered mechanism ?
Thanks !

I'm using IOCTL, and it's ok.

You get called in your driver's Dispatch under
switch (irpStack->MajorFunction)

{

case IRP_MJ_DEVICE_CONTROL:

switch (irpStack->Parameters.DeviceIoControl.IoControlCode)

{

case YOUR_OWN_IO_CONTROL_CODE1:

case YOUR_OWN_IO_CONTROL_CODE2:

...

}

}

See the article "Extending the PassThru NDIS IM Driver" at www.wd-3.com.

Use NdisMRegisterDevice -- it will create a device and symbolic link for
you. The MUX, PASSTHRU and NETVMINI samples show how to do this.
