Comment 1 for bug 1241230

We should follow "The standard (IEEE 802) format for printing MAC-48 addresses" - http://en.wikipedia.org/wiki/MAC_address, the MAC address hexadecimal digits are separated by hyphens (-) or colons (:), so have to make sure we store one Single format(such as colons) in the database, convert to colons if the input MAC is separated by hyphens, compare the existing MAC with same delimiter, then the comparison logic is working.

I will submit the code change to review.
