    Be consistent please, surround + with spaces.

This is an extremely poor and misleading description of your change.

The original code was accessing the MAC address properly at buf[5] by
starting the iterator 'i' at 5.

The bug is that the indexing of dev->dev_addr[] is incorrect.

Please describe your change more accurately and resubmit this patch.

Thanks.
