The following media types and options (as given to ifconfig(8)) are supported:
 
 
autoselect
Enable autoselection of the media type and options (default).
 
 
100baseTX mediaopt full-duplex
Set 100Mbps (Fast Ethernet) operation and force full-duplex mode.
 
 
100baseTX mediaopt half-duplex

10baseT mediaopt full-duplex

If no media options are present, the ef driver places the card into autoselect mode.
