    openvswitch: Per cpu flow stats. · e298e505
    Pravin B Shelar authored
    With mega flow implementation ovs flow can be shared between
    multiple CPUs which makes stats updates highly contended
    operation. This patch uses per-CPU stats in cases where a flow
    is likely to be shared (if there is a wildcard in the 5-tuple
    and therefore likely to be spread by RSS). In other situations,
    it uses the current strategy, saving memory and allocation time.
