They do work pretty well -- I haven't had many problems with them under FreeBSD. There are also tons of motherboards that have these chips onboard. (two of my home machines have onboard 82550/82559 chips) So it's kinda hard to get away from them. What would you recommend instead? There are other chips available, certainly, but some of them have serious hardware bugs or design flaws. e.g., look at Bill Paul's comments in the rl(4) driver, or Mike Silbersack's message on -arch from yesterday about coming up with some crazy work-arounds to make vr(4) hardware work properly. > just no point in using it in new designs. Maybe so, but it would be hard to convince vendors to stop putting them on motherboards. That's where most people will find these chips nowadays, anyway.
