Commit If2539f94b5479f0d6afa64c973082cbe8c5309ac made get_random_mac more versatile. However, in the process it introduced incompatibilities with the current behavior of randomizing mac as outlined in the respective bug report. This patch reverts the logic of get_random_mac back to its original behavior for backwards compatibility as we suspect no one is relying on the new behavior from If2539f94b5479f0d6afa64c973082cbe8c5309ac. Change-Id: I047ff3e17c19fc80a47d3c73ee955103a71d2b30 Closes-Bug: #1720046
