I've used these D-Link cards, and haven't found their performance any
different from others (such as the older DFE-570TX with the nice Dec Tulip
chipset); however I've not tried to max out the bandwidth - I'm normally
dealing with an Internet link of <2Mbps and very little local inter-subnet
traffic.
Can you try a different card (either another DFE-580, or something other than
a DFE-580, or four single port cards) to see whether the problem really is
tied to the card?
I can't quite see why a particular card would work normally but have a problem
with IP aliasing...
