Hello, i need to write a little personal patch in the bridge code. For this patch, i need to know the original src and dst mac addresses of the packet incoming to the bridge. As i work on a brouter (some packets are bridged, some are routed based on ebtable rules), packets that are routed have their mac addresses modified by the IP stack). I put a software probe in br_input.c::br_handle_frame( ), but there, the dst mac address is already replaced by the bridge local mac address. My question is: where must i put the probe to get the original src and dst mac addresses? At the driver level? In the bridge, but where? Thx in advance. PS: please CC to louis.croisezATgmail.com, because i am receiving the digest once per day.
