Seems there is a spacing issue with these commits... as every line has changed in the modified files.

remove 00:00:00:00:00:00 checks

Why do we want this?

@balupton Whitespace changes are an issue, but to see the diff without them, you can add '?w=1' to the diff view like this

@caasi Seconded @balupton 's question, adding the 00 checks was part of resolving #1 , reverting that change will make the system test work with Travis, but are fairly necessary otherwise.

Also, this would need to be updated for the 'ip link' output I added, as the first column is just an index number.

@balupton @StephenBrown2 Sorry about the whitespace changes.

@StephenBrown2 I will check if I can merge it to the HEAD in a day or two. I can not access to my Windows machine right now.

This got paused for personal delays. Added back to my workload.

Try to fix #2 by filtering input with interface name and close this issue for now.
