Why?
I would be strongly surprised if empty ebtables tables would do that to your performance. Have you tested the performance with a kernel without applying the bridge-nf patch, so only the ebtables patch? > 2) Is it possible to configure the bridge such that > will either use or not use the bridge filtering code? > Since not all the bridges will need to be filtered I > would like to at least retain the performance on those > bridges that do not need to be filtered. No, that's currently impossible. cheers, Bart _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
