Hi Ingo,

i also tried ftp now and found the same performance problems. ifconfig also shows a lot of frame errors (looks like one frame error is reported for each received packet). Interesting fact is that only download is affected (both ftp and http). NFS is also not affected (that's what i mostly use here).

However, even with a flood-ping (ping -f -s 1472), i can't trigger the frame errors i get for ftp...

Additional, i noticed that the card somehow always operates in promicious mode. tcpdump -p still shows all packets on the network. Maybe the selection of speed/mode has to be done before setting up the 8390 chip...
