Filter driver for NDIS miniport

NTDEV

Hi, All,

Does anyone know if a NDIS miniport driver can have a lower filter driver?
If yes, how to implement? Any sample code available?

Thanks in advance!

I don’t think this is possible. NDIS drivers are unlike most other
drivers, in that they operate in the context of the NDIS framework.
What are you trying to accomplish? Perhaps an IM driver would do the
trick.

What do you mean “lower fiter driver” for miniport? If you’re about hooking
MiniportXxx functions there’s some problems when hooking functions for
receiving packets (NdisMXxxIndicateReceive). For sending packets there’s no
problems and you can find sample code at http://ntdev.h1.ru/ndis_fw.html
(it’s under construction and it’s not “trusted”)

But you’d better use IM driver as previous poster said for stability
reasons.
