Hmm, did you see problems on 100 HDX as well, or only on 10 HDX?

FWIW, I haven't seen any problems when testing my new EMAC driver with 
100Mb hub, maybe it's only 10Mb related.

Anyway, this is first time I'm hearing about half duplex problems, 
Matt just mentioned them on IRC to me.

I'll try to do some tests this weekend, although I have to admit half 
duplex doesn't seem very important these days, nevertheless, if this 
can be fixed, we better do this :).
