Hi Stephen ! So I now have the driver working with the patches I gave you. However, when I set it up with a 100bT link and transfer a huge file from another machine (about 10MB/sec throughput), I get a few of these in dmesg

(That's what I get for about 600MB transfered). The other side is a sungem, I haven't yet had a chance to test with something else, in case it's actually a problem there, though. Any idea ? I'll do some tests with some other chips at the other end (will try 1000bT too) later.
