Enrico,
For this, you want to open a PF_NDRV socket to send out a raw
ethernet packet. Take a look at the sample code BSDLLCTest
<
http://developer.apple.com/samplecode/BSDLLCTest/BSDLLCTest.html>
This sample demonstrates the technique to open a PF_NDRV socket,
which requires root access, then demonstrates both the send and
receive of packets using this socket.
Sending raw packets is straightforward, but the sample is designed to
receive LLC Ethernet frames. You'll need to tweak the sample to
receive a phase I Ethernet frame for a tcp packet, if this is within
the scope of your project.
