How to develop a miniport-intermediate-driver: for a NIC with multiple interfaces?

Hi:

I am developing a Miniport driver for a NIC.
The NIC has 1 - 4 channels depending on HW model. My goal is to create 1 - 4 network interfaces. Each interface has its own MAC and IP address.

I believe I should make a miniport-intermediate-driver:

The single drive will handle HW interface(PCIe memory I/O) and expose logical adapters.

Now, I call NdisMRegisterMiniportDriver() in DriverEntry(). InitializeHandlerEx() gets called and I call NdisMSetMiniportAttributes(). Then 1 network interface is created.

I have many questions. But I would ask the first 2:

  1. I don't want to expose the interface for the physical device. I just want to expose the logical interfaces when I detect the channels on my HW.
    How do I prevent the physical device interface being exposed?
  2. How to get the HW interface?
    My driver used to be a generic PCIe device driver. I called WdfDriverCreate() in DriverEntry() and gets the PCIe I/O address in EvtDevicePrepareHardware(). From there, I can access to the HW.
    However, EvtDevicePrepareHardware() was not called if I call NdisMRegisterMiniportDriver().

Many thanks for the answers. And feel free the correct any of my saying if they were wrong.
