Hello everyone,

    I encountered a performance issue regarding bridge, please let me
know your thoughts:

        I am doing the stress test against bridge with two scenarios

        I created two br2684 interfaces (nas0 and nas1) on a Linux box
and create 1 VLAN interfaces (eth0.32) on eth0 and then do the
followings

       1. Bridge nas0 and eth0.32
       2. Bridge nas0, nas1 and eth0.32

Start 100% traffic load on nas0 for scenario 1, no traffic loss Start
100% traffic load on nas0 and nas1 for scenario 2, 40-50% traffic
mis-inserted /duplicated.

If I added more nas interfaces to the bridge

# of the mis-inserted/duplicated packets will increase up to 100%

I am on kernel 2.4.31,

Please let me know your thoughts!

Thanks!
