Are you using straight RSS without any modifications? By default the Toeplitz hash that RSS uses is not a bidirectional hash. i.e., each flow of a connection ends up on a different NIC queue. As a general rule though, you should try to avoid anything that could result in packet reordering.
Another question, how are you making Bro attach to the various NIC hardware queues?
