** Patch added: "0007-arm-dts-am33xx-Add-syscon-phandle-to-cpsw-node.patch"
   https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1452628/+attachment/4392976/+files/0007-arm-dts-am33xx-Add-syscon-phandle-to-cpsw-node.patch

** Description changed:

  SRU Justification:
  
      Impact: after every reboot, the nic on the beaglebone gets a
  completely different MAC address.
  
      Fix: Apply the patches, recompile and reboot.
  
      Testcase: Try booting two times in a row with and without the
  patches applied and check if the MAC address of eth0 changes or not.
