I actually have an if_de card on my desk, thanks to Mark Murray who dropped it off a couple of days ago, but no computer to put it in. I just moved to Cambridge, UK from Washington, DC, and have only notebooks with me. As far as I know, no pccard form factor if_de cards were ever made, although I'm willing to be corrected on that point, and accept one willingly :-). I'm doing most testing on a remotely administered test cluster, so maybe the answer is to get it shipped there to put in a box. I'm beginning to wonder if the race isn't that the if_de interrupt thread runs between the point where a packet is queued for the interface and the if_start runs out of a task queue. I'm still making may way through the if_de driver to understand how it all fits together, however.
