NDIS 6.1 - Miniport General Attributes and HDS

Hello,

I am trying to implement Header Data Split(HDS). NDIS mandates drivers to have a backfill space in data buffers, but when NET_BUFFERs are created with backfill space, tcpip driver crashes upon packet receiption. There is a Databackfill member in General Attributes structure. Should I be setting it to non zero ?

Thanks,
Prabhath
