Retire IP_RSSCPUID ; the right thing to do is query the RSS bucket;
map the bucket to an RSS queue, then map the queue to a CPU ID. This way the bucket->queue and queue->CPU mapping can change over time. Introduce IP_RSSBUCKETID - which instead looks up the RSS bucket. User applications can then map the RSS bucket to a CPU.
