Hi,

I compiled the driver staticaly into the kernel to see if it affects performace
and the result is pleasant (I was getting about 10-12 Mbit with the driver as
module on those slow machines):

after setting frameburst to 5000 (maximum allowed by windows driver) on both
machines (./setoid eth0 0x1b000008 136 19 0 0):
