Thanks for the quick response, In theory I know what to do -> strip mac from/to, push a new header, put the mac from/to back on the packet and send it. But what exactly do i need to copy? lets say that's my function signature: void processPacket(const struct pfring_pkthdr *h,const u_char *p, const u_char *user_bytes) which one has the entire packet? and how do I replace my modified packet with the one that was received?
