Hello Andy, I work primarily on the igb driver. Thanks to Emil for helping out with this. "Upstream" is kernel source from kernel.org. We provide two equivalent igb drivers, the latest upstream kernel and an out of tree driver located at Source Forge. The driver that comes with your distribution is based on the upstream version but can be modified by the distribution vendor. The RSS parameter is configurable at driver load with the out of tree driver only. This kind of configuration is not allowed upstream. The upstream version configures RSS as max number of cpu's or max queues, whichever is less by default. The out of tree default is a single pair of queues. You can see what is configured by the driver load in this regard by running dmesg. What are you trying to accomplish and I'll try to help you get there.
