Hi Steve,
I checked it and your doubt is right. MTU is an issue in my case. I’m
appending a trailer of 5 bytes to the original packet. So when original
packet size becomes > 1495, miniport driver simply drops my new packet which
now has size > 1500.
I thought of two solutions:
- Fragment the packet and send two instead of single packet. On the
receiving side, I don’t need to handle the fragmentation as it will be
handled by upper layer. - Set the MTU to 1495 instead of 1500.
The first option will take time to implement. Is there anyway of setting the
MTU ?
Thanks for your response,
Amit Manocha
