I'm trying to find resources how to use the PacketDirect library but almost no documentation exists. The only high level explanation i found is here: https://learn.microsoft.com/en-us/windows-hardware/drivers/network/introduction-to-ndis-pdpi#packetdirect-concepts also couldn't find any sample code that demonstrate how to use it.

I would like to leverage the PD cabalities of my NIC but i'm starting to question wheter this functionality is actually supported and possibly replaced.

In case it is supported would be nice to get access to a documentation about the "PacketDirect Client Interface" and in case it isn't supported my question is what is the new library that can provide kernel bypass on Windows (closest to the hardware but also doesn't require to reimplement the miniport driver) ?
