(Small nit: The card is always in duplex mode. The
question is whether it's half-duplex or full-duplex.)
It would be helpful if you just gave us the output of
``ifconfig fxp0'' from your box. I guess it looks
something like this:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet **.**.**.** netmask 0x******** broadcast **.**.**.**
ether **:**:**:**:**:**
media: autoselect (100baseTX <full-duplex>) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP
(There might be additional stuff if you enabled IPv6.)
The interesting things are the bottom two lines. The last
one enumerates the media modes that your card supports, and
it should look exactly like the one above.
The preceding line describes the currently active media.
If you didn't change any of the defaults, _and_ if the
media and duplex mode were detected correctly, then it
should look like the one above, too. Notice the word
``<full-duplex>'' there. If it isn't there, then the card
is in half-duplex mode. See the ifconfig(8) and fxp(4)
manpages for information about how to change that.
The word "SIMPLEX" in the first line has got nothing to do
with the media or media options of the interface. You can
safely ignore it.

Oliver
