Seems you need to build the driver. It uses the alx driver module

If you can run update (maybe wirelessly), the needed alx driver will be brought in with the new kernel. If not, try downloading a compat-wireless... package (pick the right version for your kernel) and getting the alx from that -- trouble is this way may interfer with wireless, as many other (unwanted) drivers will be brought in.
