It takes about 1 Watt more energy to have a 1G link vs a 10Mbps link, even when there is no traffic. So during suspend with WoL enabled, phylib tries to reduce the link speed to the lowest common speed, hopefully 10Mbps, by only advertising that one link speed. On resume it goes back to advertising the full link capabilities. So one of the down/up you are seeing might be this. Andrew
