Protocol Request to send Packet1

NTDEV
1

Packet1 is allocated by a protocol driver , filled with data, and passed to
the Nic Card so that the data can be sent on the network.

Does Nic Card send the Packet1 or encapsulate Packet1 in Packet2 and send
Packet2 ?

Thank

The NIC card will send the packet that you passed to NdisSend unless there
is an NDIS Intermediate (IM) filter driver between your protocol and the
actual NIC miniport. If there is a NDI SIM filter driver in the path, then
it may modify the packet and will re-wrap it in at least a “fresh NDIS
packet descriptor”.
