As I recall, the Realtek chip on the RCM3000 does not support auto-negotiation. The FD/HD control is a bit in one of the configuration registers. 

 The ASIX chip on the RCM3900 supports auto-negotiation, and it is enabled by default. This can be overridden by a control field in one of the PHY control registers though, so that would be the place to look.
