    try 100baseTX with exact case sensitivity. i.e. lower-case 'b' and upper-case 'TX'.

    from man 4 em:
         autoselect Enables auto-negotiation for speed and duplex.

         10baseT/UTP Sets 10Mbps operation. Use the mediaopt option to select
                      full-duplex mode.

         100baseTX Sets 100Mbps operation. Use the mediaopt option to select
                      full-duplex mode.

         1000baseSX Sets 1000Mbps operation. Only full-duplex mode is supported
                      at this speed.

         1000baseTX Sets 1000Mbps operation. Only full-duplex mode is supported
                      at this speed.
         The em driver supports the following media options:

         full-duplex Forces full-duplex operation

         half-duplex Forces half-duplex operation.

         Only use mediaopt to set the driver to full-duplex. If mediaopt is not
         specified, the driver defaults to half-duplex.

    If that doesn't work either, I am not sure if XF fiber intel gig-e cards are
    capable of 100Mbps.
