What module type would an LKM to interface with NDIS drivers be?

 From what I've read, it may be a device driver module... or it may be a 
miscellaneous module... I'm just not sure.  The intended purpose of the 
module is to allow the use of Win32 NDIS drivers for 802.11 wireless 
network cards.  Is there a "well-defined or well-used interface for 
extension" of such a module?

Yeah, I know, someone embarking upon something like this should be able 
to figure it out for his self, but I'm *special*.

Thanks,
Mike.
