Bug description:
  When trying to configure a virtual NIC to DHCP with no IPv6 addresses using Hyper-V's integration services, a configuration file similar to the following is generated:
  HWADDR=XX:YY:ZZ
  DEVICE=eth0
  BOOTPROTO=dhcp

  When running the hv_set_ifconfig script with this script as an argument (executed by IS, most likely the KVP daemon; I ran it manually in order to debug), it fails with the following stderr (stderr is muted, the script must be edited to retrieve this information, so the line number is offset):
    File "hv_set_ifconfig", line 171, in <module>
      output = ["auto "+" ".join(autolist)] + output
  NameError: name 'autolist' is not defined

  Editing the script so that autolist is defined in all flows resolves
  the issue and the script successfully sets the interface to use DHCP
