It's kind of the classic admin shutdown but I can guess people .. well anyway. Another argument is that you actually save power and if you have 30k machines out of which 20k don't need the 2nd port and you can save .2W it's saving around 4kW just by turning PHYs off. > Just saying that my FreeBSD drivers have not done so forever :) And I am not saying they have to do it by yesterday;) The very worst I'd suggest is to add a sysctl so people can control it that the PHY should be off if the interface goes down if you cannot find a consensus with your coworkers. /bz -- Bjoern A.
