 I also noticed this performance degrade when doing the QNX tulip driver. It can
however be fixed. If you bump up your CACHELINE / Burst size values (PCI CACHELINE 
/ CSR0), you will be able to get the Lite-On to perform just as good as the 21143.

And on some machines it will perform slightly better. It doesn't seem to be affected
at all by the Rx Overrun/PCI errata of the 21140-->21143's.
