Hi!

Current kernel: linux-3.0.17-r115c
Download speed:  745kB/sec

Previous kernel: 2.6.32-r78
Download speed: 1MB/sec

I noticed the regression in speed for ks8851 driver (Micrel
KSZ8851-SNL). I used this part with kernel 2.6.32 and the speed was
1MB/s. Then the driver code was changed and for current Linux version
linux-3.0.17-r115c the speed is 745kB/s. 25% speed reduce is indeed
noticeable.

I use Angstrom Linux built in OE environment.
Target board is Beagleboard C4.
