This is standard behaviour. If one port is forced to full duplex and 
isnt' autonegotiating, the client side port will recieve no negotiation 
and assume half-duplex.

You generally shouldn't force the properties of an ethernet port unless 
you're using poor hardware with known issues (like some old cisco and 
3com gear).
