Bug description:
  [SRU justification]

  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 MAC address that is
  not in the exclusion list, eth0 is persistantly named for the first
  NIC seen. If a user rebundles, or the machines has its MAC address
  changed, it will lose network connectivity.

  Fix : Add Microsoft provided and requested MAC addresses to the
  Hyper-V list of excluded MAC addresses for peristent naming.

  Test Case :
   - Launch Hyper-V VM with MAC address in each of the ranges
   - Install updated Udev/systemd
   - Delete any existing udev rule
   - Reboot and confirm that no new UDEV rule was added

  Regression : None expected.

  [ORIGNIAL BUG REPORT]

  Currently /lib/udev/rules.d/75-persistent-net-generator.rules includes
  the following ignored MAC prefix for Hyper-V:

       # ignore Hyper-V virtual interfaces
       ENV{MATCHADDR}=="00:15:5d:*", GOTO="persistent_net_generator_end"

  As Microsoft expands its public cloud offering it may need to utilize
  additional MAC address prefixes.  In addition to 00:15:5d, please add
  the following Microsoft-owned MAC prefixes to this list:

   00-03-FF	Microsoft Corporation
   00-0D-3A	Microsoft Corp.
   00-1D-D8	Microsoft Corporation
   00-12-5A	Microsoft Corporation
   00-17-FA	Microsoft Corporation
   00-22-48 	Microsoft Corporation
   00-25-AE	Microsoft Corporation
   00-50-F2 	MICROSOFT CORP.
   28-18-78 	Microsoft Corporation
   50-1A-C5	Microsoft
   60-45-BD	Microsoft
   7C-1E-52 	Microsoft
   7C-ED-8D	MICROSOFT
   DC-B4-C4	Microsoft XCG
