NDIS Protocol Driver?

I have read this paragraph 5 times and I'm still not sure what it means
"An NDIS protocol driver can support Transport Driver Interface (TDI) at its
upper edge, or it could export a private interface to a higher-level
kernel-mode driver, possibly through a transport stack of drivers, including
one that supports TDI at the top of the stack. For example, an NDIS protocol
driver can be the lowest module of a multi-module transport implementation
of a standard protocol, such as TCP/IP, with TDI support in the highest
module"

I know exactly what TDI is in win2000/XP and I thought winCE doesn't have a
TDI support... in 2000/xp and others TDI is the interface above TCP/IP stack
but it seems that in wince is bellow the TCP/IP....

could somebody please explain a bit on the paragraph... what would be a
scenario that one would want an NDISProtocol with upper edge of TDI??

You are correct that CE does not expose/support the TDI interface for use by
3rd party protocol drivers. The documentation is misleading, I will file a
bug to get it corrected.

Thanks for finding this and reporting it.
