Hi,

I'm sorry to say that the packet drop issue is still not solved
with a DF580-TX using four of these chips:
        Class 0200: 1186:1002 (rev 12)
        Subsystem: 1186:1012

Sending bi-directional streams of UDP-packets with 200-byte payload
through the machine I get zero packet loss and 15% CPU usage with
either eepro100 or tulip-based cards. Using the DFE-580TX I get
15% packet loss and 25% CPU usage. Ifconfig also shows packets
being dropped:

          inet addr:10.230.0.1  Bcast:10.230.0.255  Mask:255.255.255.0
