Raw packet capture and sending

Hi !

I have device(ARM920T) and Linuxm, that runs on it.

I look for ways to make the next things:

1) Make my program to capture raw packets and forward them to the
server-appplication, without kernel to process this packet to my application
(i.e. avoid packet duplication)

2) Send received packet to the server-application.

I found a way to make program capture raw packets, but kernel process these
packets and server-application receives packets from kernel.

How to make kernel not to process packets, which I'm interested in ?

Hi,

Are you using libpcap in your program? I think you should try to
incorporate *your* program into the receiving application itself. That
way, the application will receive and process the packet copies.

If you find another way of doing this please let me know because I need
to do a similar thing ;-)
