If there was a link-mode change (100-to-10-base, 1/2 to full duplex) OR
if the chip status overflowed (tx packets, rx, packets, errors, etc) OR
if the transmitter aborted (unplug when active, etc.) THEN
reset and reprogram the chip (after telling you something wicked
happened IF verbose debug is enabled).
You can turn OFF verbose debug (set debug to 1) and you won't have
the message.
