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
100baseTX Sets 100Mbps operation. Use the mediaopt option to select
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.
