Take a look at the WDK NDISPROT sample and how it implements the capability
to send a packet from an application.

Good luck,

From Ndis IM, you simply NdisSend or NdisSendPackets.

Most common mistake is the forget that the send complete handler must handle
packets sent this way differently from pass-through packets.

I wrote a short note about this. OP should see:

“Common Error in Sending or Indicating Custom Packets from a NDIS Filter
Driver” at the URL:
