TDI endpoint from socket handle?

NTFSD
1

I have a user mode application and a device driver, and I would like my
device driver to perform some portion of the network I/O from within the
kernel using TDI.

Is it possible for a kernel driver to obtain the TDI endpoint used by a
WINSOCK socket handle? I can create an IOCTL in my driver and have the
user mode application pass in the handle to the socket. Is there any way
to dereference this handle and get a pointer to a TDI connection point?

Thanks tons in advance!
