Ok, I guess card<something> is best suggestion so far. If it is really status for specific PCI card, then that's the right way to name it. Maybe "pciecard<>" would be even better. Plus we really should have documentation somewhere so that next person trying to name a LED on a card ends up with same answer. > I can use name 'fru' instead of 'card' which is standard name and stands for > 'Filed Replicable Unit'. Such name will be good for line cards, for fabric cards, > for power units, FANs etcetera. Best regards, Pavel -- http://www.livejournal.com/~pavelmachek
