> different queues instead of falling back to a single queue. Without this patch,
> attempting to disable RSS would not work as expected. This patch fixes the
> bug by clearing the lookup table used by RSS such that all traffic is assigned to
> a single queue.  This patch also addresses the issue of reinstating  the lookup
> table should RSS then be re-enabled.

RSS no longer functions when disabled, packets all go to queue 0.
