I am unable to induce any duplicate packets using the current
netdev-2.6.git upstream branch (which should be the same bonding driver
as you're using). I tried it with and without VLANs, using ping to
various addresses (unicast, subnet broadcast, all-1s broadcast). I'm
using a Cisco switch, and I'm issuing the IOS command "clear mac
address-table dynamic" to induce it to (briefly) flood traffic to all
ports.
The only duplicates I see are ping pointing out duplicate
returns from the multiple stations on the network. I don't see bonding
delivering two copies of the same packet.
Using the unmodified 2.6.16.1 kernel, I do see multiple copies
of the same packet from a ping to the broadcast address using the method
I describe above.
I am using a different network device (tg3), although I'm not
sure how that would affect this.
Under what circumstances are you seeing duplicates, and what
type of traffic is it?
