Title:
  dhcp fails if extra_dhcp_opts for stateless subnet enabled

Status in neutron:
  Fix Released
Status in neutron kilo series:
  Fix Committed

Bug description:
  vm on a network having IPv4 and IPv6 dhcpv6 stateless subnets,
  fails to get IPv4 address, when vm uses a port with extra_dhcp_opts.

  neutron creates entries in dhcp host file for each subnet of a port.
  Each of these entries will have same mac address as first field,
  and may have client_id, fqdn, ipv4/ipv6 address for dhcp/dhcpv6 stateful,
  or tag as other fields.
  For dhcpv6 stateless subnet with extra_dhcp_opts,
  host file will have only mac address and tag.

  If the last entry in host file for the port with extra_dhcp_opts,
  is for dhcpv6 stateless subnet, then dhclient tries to use this entry,
  to resolve dhcp request even for IPv4, treats as 'no address found'
  and fails to send DHCPOFFER.
