    Subject[PATCH 19/24] net, diet: Make RPS configurable
    Date
    From: Andi Kleen <ak@linux.intel.com>

    Multiple receive queues are not needed on small systems,
    so allow disabling them.

    This is already disabled with !SMP, but it also makes
    sense to disable on very small SMP systems (like
    dual core SOC)

    Can be worth ~30k code and 6k data

    text data bss dec hex filename

    6893698 1392544 634880 8921122 882022 vmlinux-wo-rps
