I'm not sure if it is relevant for the 2008.0 release but recently I found a bug in the USB asix network driver for a Gigabit Adapter I have here at home. It works fine for 1000baseT/Full but it's broken for at least 100baseT/Full. I already reported this issue upstream and I provided a quick and untested patch. It now works for me - but I'm not sure if this is the case for other system setups as well. Just wanted to mention it here. If it's important for another working network driver in the 2008.0 release please mark it as a blocker.
Thanks, will track upstream bug
