Subject: Re: [PATCH v3] rps: optimize rps_get_cpu()
By the time you hit this code (at least on machines that make sense for
RPS), you already have the ethernet header, IP header and transport
ports in cache, no?
I think the sport << 16 shifting is avoided - but i dont think theres
any effect on mem access.
cheers,
jamal
