Most likely related to the PHY power being turned off. X540 got a fix for that. You might want to look through FreeBSD's e1000 driver looking for the phy power bits relevant to your model (determine MAC and PHY ids and chip family and then follow the code). I've looked briefly some time ago but nothing has immediately popped at me.
