  This seems somewhat dependant on the kind of card used.

  A SMC Etherpower 10/UTP behaves correctly, if disconnected and
reconnected.

  A D-Link (DE-650?) with BNC/UTP did not do this properly.  Fooling about
with "ifconfig de0 -linkX" did manage to get it working again.

  I think the problem is that some cards don't properly indicate whether a
particular interface is working, or not working, to the driver, except on
power-on.
