jay,
  Under *BSD this is all handled with the ifconfig command. Below are  
a few snippits from the man page of ifconfig:

mediaopt opts
              If the driver supports the media selection system, set  
the speci-
              fied media options on the interface.  The opts argument  
is a
              comma delimited list of options to apply to the  
interface.  Refer
              to the interfaces' driver specific man page for a  
complete list
              of available options.

-mediaopt opts
              If the driver supports the media selection system,  
disable the
              specified media options on the interface.

Take a more complete at the ifconfig man page for more information.

-Ron
