OOB Data and Packet Extensions array in NDIS_PACKET

Hi All,

I am new to NDIS and am trying to figure out if I need to do any special
allocation to allocate OOB data area and packet extensions array for a
NDIS_PACKET allocated using NdisAllocatePacket. I see that there is a
OobOffset in the private region of the NDIS_PACKET but I do not
understand who sets it up and where it actually points. Thanks in
advance for your help.
