    Skip larger than /64 subnets in DHCP agent
    
    Dnsmasq can't handle these in IPv6 so we need to skip them to avoid
    a whole bunch of log noise caused by continual retrying of issues.

Title:
  dnsmasq doesn't like providing DHCP for subnets with prefixes shorter
  than 64

Status in neutron:
  Fix Released

Bug description:
  Trace when you enable DHCP on an IPv6 network with a prefix less than
  64.

  2016-11-15 17:33:54.321 102837 ERROR neutron.agent.dhcp.agent ProcessExecutionError: Exit code: 1; Stdin: ; Stdout: ; Stderr:
  2016-11-15 17:33:54.321 102837 ERROR neutron.agent.dhcp.agent dnsmasq: bad command line options: prefix length must be at least 64

  At a minimum we need to skip these on the DHCP agent to prevent a
  bunch of log noise and retries. We probably should consider rejecting
  enable_dhcp=True in the API when the prefix is like this for IPv6 if
  it's a fundamental limitation of DHCPv6.
