Hi Jamal and Dave,

I continued to do some testing in a minimal
environment, basically the routing between the
two ethernet ports on the mips board. Only
ethernet driver is loaded. The user-space
only has busybox.

The difference between 2.6.8.1 and 2.4.17 kernel
is 3000pps less for routing. However, the bridging
performance is the same between two kernels.

Jamal, where is the Andis gettimeofday changes
you mentioned?

Thanks.

-Song
