Using Ndis WDM with a 32 bit microcontroller

I got a microcontroller connected over a pci bridge to my pc. This controller
got its own ethernet controller, 32 bit cpu and other peripherals like gpio.
I want to use microcontrollers ethernet controller for my internet
connection. For that purpose a small driver, running on the microcontroller,
will sent me interrupts over pci and vice versa.
Is it possible to use a Ndis WDM driver and modify it to make DMA transfers
to controllers memory?(Pci bridge got a DMA channel)
Or should i develop a WDM pci driver and use it with Ndis WDM driver?
Did someone tried that before? How robust will be this model?

so, you want use your micro controller as your ethernet device to communicate
with your PC. you need to develop NDIS miniport driver and miniport driver
will NDIS_PACKET/NET_BUFFER to OS network stack.

What i forget to say is, i just want to communicate with microcontroller
ethernet controllers driver, so when it got a packet it will indicate me with
an interrupt.
My miniport driver should make dma transfers. Is it possible to map
microcontrollers registers and memory in my Ndis Miniport driver?
(My OS is XP)

Everything depends on your microcontroller hardware. Try to design a
Windows NDIS miniport driver which will talk to the microcontroller hardware
yourself.
