[En-Nut-Discussion] Full Duplex operation

[NGB]

It's the same story with the LINK led but that one works with ethernut.
I don't have the schematic handy, but if I remember correctly (which I probably 
don't) , the eeprom input is tied high, so when the realtek tries to load it, 
all bits are set to 1.
This should enable the full duplex.

> The FUDUP bit in the CONFIG3 register is read only.  Page 11 of the data
