Most work was done against master but later backported to rc2 in
terms of stability in packages. It is not a problem to revert it
back to master.

There is definitely no other place with valid MAC elsewhere in flash.
MAC in ART is fake one like 000203040506. As seen in bootlogs factory
firmware starts with random MACs and then use special init script and
nvrammanager binary utility to parse data from partition default-mac.
Can look at fullflash here http://fex.net/get/227411653165/2400918

Will look at it. Thank you.
