Let's see, get rid of the 64-bit structure alignment, dump its ability to do a reasonable amount of multicast efficiently... I hope these don't catch on considering real tulip chip based cards are already dirt cheap. ;) Ah well, good to see it supported none the less. > So far, the only card I've found that uses the Winbond chip is the > Trendware TE100-PCIE (www.trendware.com).
