Hi Mugunthan, though this patch fixes drop packets issue, it introduces another issue. Just connect both interfaces to one switch and configure different subnets. As soon as you get a broadcast you have an endless loop and network communication is not possible at all. Before this patch you could operate as if you had really two independent NICs.
