It still doesn't work well with the Lite-On Netgear cards (or the card is
really a piece of garbage). Here's a little test:

file = ungzipped 2.1.127 linux kernel (still tarred)

10.0.0.1  = SMC Etherpower II
10.0.0.51 = SMC Etherpower II
204.253.132.4  = SMC Etherpower II
204.253.132.10 = Netgear FA310TX w/ Lite-On

10.0.0.51 -> 10.0.0.1

Am I just missing something, or is this device receiving at about 1/5 the
speed of the Etherpower II?! I mean, the lower system CPU numbers are
great, but not if I'm only getting 164 kBps over *ethernet*. (BTW, there
are no firewalls involved in any of these cases.) Is this just a matter of
time before the driver gets better performance than this? Or is this card
just fatally flawed? Or is my *test* flawed somehow?

I agree wholeheartedly! Keep up the great work! (And death to
manufacturers that try to sneakily switch chips and call it a new
revision! DEATH!)
