What OS is that ? You can : unplug the cable, if the sole purpose is not to use the interface / have traffic. However, if you need the IP, for example, try to 'plump' it again, or upping it, just as if it was a brand new NIC. Give the same IP. Check the logs (dmesg) for messages that would suggest something near to hardware defect, for example. I'm not sure how NIC is up with no name. Check the respective man pages for 'ip' - something like :
Code:
ip link set name

may work for you. Use those options with caution, though.

Both interfaces point to the same hardware i.e. 00:09:3D:12:9D:5A
