[OpenWrt-Devel] Lantiq xrx200: Access to ethernet phy registers (MDIO) from userspace

I am searching for a possibility to disable Auto Negotiation of an 
PEF7072 which is attached to MAC1 of the Lantiq xrx200 switch.

The xrx200-net driver does not seem to have support for that.

Accessing the STD_CRTL register on the mdio bus from uboot with the mdio 
command works like expected.

Any suggestions how to do that from linux userspace?
