I don't know, but i would assume that you should ask this question on
the kernel bridge list (You find it under
http://bridge.sourceforge.net/), the people on this List have deep
knowledge on the linux networking/driver subsystems.

see above... But i doubt you can run this under full speed on all
interfaces (or better the pci-express ones)...

Another good question for the bridge list ;-)

  Just done that :) I needed to wait for acceptance in the list.

  Sure, I dont expect full speed. Actually, the box is overdimensioned
in the ethernet side. Think more in the 20Mbps margin for WAN to LAN
traffic and some peaks of around 100Mbps for local ethernets.

  Thanks
