In NDIS intermediate driver i capture IP packet,after doing sth,i need
route “New packet” again.
i want to use TDI to finish the routing, so i create
“\Devide\RawIp\#protocol”, build TDI IRP,IocallDriver…
ok, it is working!
unfortunately,i can’t get any way to include iphead, TCP/IP build a iphead
for my “New packet”.
When an application sends a datagram it may or may not include the IP
header at the front of the outgoing datagrams depending on the IP_HDRINCL
option set for the socket.
As TDI client, how do i send a datagram it may include the IP header?

Find the DDK’s WSHSMPLE code, which has the illustration of how setsockopt()
for TCP and IP options is implemented at TDI level.
Then find AO_OPTION_xxx flags there.
The IP_HDRINCL option is not listed there, so, add it yourself as:
#define AO_OPTION_HDRINCL 11
and run SetTdiInformation routine from WSHSMPLE. The data type is BOOLEAN.

Max,
If AO_OPTION_HDRINCL is 11(I believe you meant decimal). Which
option value is 0x0C (12)?
I was under the impression that AO_OPTION_HDRINCL is 0x0C.

Dunno, I have found that IP_HDRINCL is AO option 11 (0xb) by experiments.
