Yea, I've looked at the ifconfig man page.

ifconfig -m de0 reports the following:
de0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	media: 100baseTX status: no carrier
	supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP
	inet 131.216.18.2 netmask 0xffffff00 broadcast 131.216.18.255


However no combination of options that I can think of will select
100BaseTX <full-duplex>

I've tried ``ifconfig de0 media '100baseTX <full-duplex>'  I've tried using
mediaopts, etc.  can't seem to come up with the correct incantation.
