Add another RSS method to query the indirection table entries.
There's 128 indirection table entries which correspond to the low 7 bits of the 32 bit RSS hash. Each value will correspond to an RSS bucket. (Then each RSS bucket currently will map to a CPU.) This is a more explicit way of figuring out which RSS bucket is in each RSS indirection slot. It can be inferred by the other methods but I'd rather drivers use something more simplified and explicit.
