how to communicate between ethernet cards

[crunchii]

Hi:
i m working on network intrusion detection.In this project i have to capture the raw data from one nic and send it to the other nic on the same computer by remaining below the driver of the nic so that the data can't enter the TCP/IP stack of the Linux kernel 2.4. can u kindly guide me in this regard what should i do and which stuff should i study in order to find a hardware solution for this.
regards
crunchii
