Subject: [Bridge] Information needed about bridge c code
Date: Wed, 1 Feb 2006 10:31:07 +0100 [thread overview]
Message-ID: <34d8b2fe0602010131n884f73bt@mail.gmail.com> (raw)
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.
