Title:
  [SRU] Add Microsoft-owned MAC address to 75-persistent-net-
  generator.rules

Status in systemd package in Ubuntu:
  Fix Released
Status in udev package in Ubuntu:
  Invalid
Status in udev source package in Precise:
  Fix Committed
Status in systemd source package in Trusty:
  Fix Released

Bug description:
  Impact: As Microsoft expands its public cloud offering it may need to
  utilize additional MAC address prefixes.  If a user launches a Cloud
  instance when the MAC address is from a Microsoft-owned MAC address
  that is not in the exclusion list, eth0 is persistently named for the
  first NIC seen. If a user rebundles, or the machines has its MAC
  address changed (e.g. VM resize or VM is moved to another host), it
  will lose network connectivity.

  Fix:  Please add the following Microsoft-owned MAC address to the 75
  -persistent-net-generator.rules file:

       00:25:ae  Microsoft Corporation

  Test Case :
   - Launch Hyper-V VM with MAC address with prefix 00:25:ae
   - Install updated Udev/systemd
   - Delete any existing udev rule
   - Reboot and confirm that no new UDEV rule was added
