Unknown network interface

[Robert Fitzpatrick]

I upgraded an old server from 9.3-RELEASE to 10.3-RELEASE and the 
network card is not recognized. I went into bsdconfig Network Interfaces 
and it shows 'unknown network interface type'. However, the card model 
is D-Link DFE-530TX+ and listed on the supported hardware list. Is there 
something I can do to get the card working? I also have a Trendnet 
TEG-PCITXRL gives me the same thing.
