The current diagnostic/setup program will show the EEPROM settings, but does
not allow changing them.

The 8139B allows setting following EEPROM values that we do not support
   Boot ROM size
   Tx and Rx flow control
   An initial forced speed and duplex setting.
   LED meanings
   Initial power state.

It would be trivial to add any of these -- the setup program already
includes the code to write the EEPROM.  But the user interface and
documentation are problems.
    I've already used up most of the good option letters
    The documentation must be consistent across setup programs.
    Many RTL chips (rtl8129, rtl8139, rtl8139A) don't support features such
    as flow control.
