One other question, how much speadup do you get with async probe of PHYs? Is it really worth the effort?For me it's a reduction of ~170ms, which currently accounts for roughly the 25% of the time spent before starting userspace (660ms vs 490ms, give or take a couple of milliseconds). That's due to the large reset time required by the PHYs to initialize
170ms seems like a long time for a reset. Maybe check the datasheet and see what it says. Andrew
