Yes, I realize that since you are the latest > person submitting something in that area, you are being selected :) I see the merit of your proposal to come up with a generic mechanism to configure Ethernet LEDs, however I can't justify spending much of my work time on this. If it is deemed useful I'm happy to send another version of the current patchset that addresses the reviewer's comments, but if the implementation of a generic LED configuration interface is a requirement I will have to abandon at least the LED configuration part of this series.
