NDIS (and OS/Platform) defines for protocol driver?

Hello

My protocol driver runs on Windows server 2k3 sp2 and 2k8 server.

I need to send NET_BUFFER as MediaSpecific OOB item to my miniport both on 2k3 and 2k8 servers.

For protocol drivers are there any standard NDIS #defs like they are for miniport (NDIS61_MINIPORT, NDIS_SUPPORT_NDIS61 etc).
How do I bring in NET_BUFFER definition on to my Win2K3 Advanced Server driver version which is NDIS51 ?

Also let me the standard windows #defines for the folloiwng

Windows Server 2003 SP1, SP2
Windows Server 2008 (all server versions) and

i386, am64, ia64

–thanks
