Ndis 5 Miniport Driver

NTDEV
1

Hi,

I am writing an Ndis miniport driver that supports offloading of TCP,
IP checksums and segmentation. What kind of flags or registers do i need
to set and at what point of time do i set these to support the above?

Also, I have one more question. What kind of interrupts should I be
looking for? (during the transmit and receive processes and how do I
process them)
OS: Win2K.

Anticipating help,
Thanks,
CSK

Hi Chaitanya,

This happens at the load time of the driver as NDIS asks various queries to the miniport and a few of thse is TCP/IP Checksum offloads are also in that so just look at the OIDs.

Good Luck,

Assuming you have the DDKs, look at the *ebx* exaample under ndis sample
directory. The examples are (xp, win2k) for intel’s 8255* controllers, and
they very very useful examples to follow for your project …
