RNDIS transport driver for SDIO

NTDEV
1

Hi,

I need to develop RNDIS transport driver for SDIO (usb8023.sys functionality for SDIO instead of USB). Is there any sample code or document which can help me to develop this module (need to know the upper entry points/interface of RNDIS transport driver).

What’s a specific need to plug into an undocumented RNDIS miniport lower edge? A standard well documented solution encouraged by Microsoft for your case is an NDIS-KMDF SDIO driver. You could talk to the RNDIS folks at the rndisfb at microsoft but I can’t think of a worthwhile reason to pursue your route.

I think what you are going to be writing is an NDIS Miniport driver
(NDIS/WDF or NDIS/WDM) that has a lower-edge performing I/O to the SDIO
stack. The fact that the messaging will be formatted per the RNDIS
specification is hidden since AFAIK there is not system supplied component
that provides RNDIS operation over SDIO (that is your problem) nor any
component division of the system supplied RNDIS support that allows you to
plug a different ‘bus’ in under the existing miniport driver.

You might note in the diagram at
http://www.microsoft.com/whdc/device/network/ndis/rmndis.mspx that the
Miniport+USB Transport (between them somewhere is the RNDIS protocol
implementation) is a single driver.

Is there a ‘standard’ in the SDIO device community that promotes RNDIS?
(Sorry, this is not bus I pay too much attention too). If so, perhaps the
industry association has plans to promote the creation of a single
‘standard’ driver like was created for RNDIS/USB.

Good Luck,
Dave Cattley
