How do we get leds working? Well, frankly, I never thought the TX LED was a super good idea - but it had been supported by the original code IIRC, so never removed. Some people like frantic blinking I guess ;-) But I think the problem also applies to the throughput trigger thing, so perhaps we need to stick some LED feedback calls into other places, like _noskb() or provide an extra way to do it? johannes
