many thanks for this.
Looks good - i'll try it on linux later.

For now i have to bring this stuff up in vxWorks first.

For U-Boot i have some bad hack running, as told.
I will start a implementation for "fixed-link" resp. "fixed-phy" in 
u-boot. Maybe i can provide some patch for RFC during next week.

cheers,
Hannes
