The commit message is supposed to answer the question "Why?". Isn't reducing the voltage going to make the device non conforming? Why would i want to break it? I could understand setting it a bit higher than required to handle losses on the PCB and connector, so the voltages measured on the RJ45 pins are conforming. Also, what makes the dp8382 special? I know other PHYs can actually do this. So why are we adding some vendor specific property just for 100base-tx? Andrew
