At the risk of typing into Michael's keyboard, chances are, what the NIC does is 
follow Microsoft's specs for RSS, which as far as I can tell, discusses hashing 
either just on the IP addresses (v4 or v6) or the IP addresses and TCP port 
numbers, so unless Broadcom has an enhancement/extension, if the traffic 
arriving is not TCP/IP and not multiple connections, it probably does not get 
spread-out.
