Title:
  Arping doesn't work with IPv6

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

Bug description:
  Neutron tries to query if host exists by apring, but in IPv6 there is no ARP, but only NDP.
  Some other tool should be used, for example:  ndisc6 (http://www.remlab.net/ndisc6/), ndp (http://www.freebsd.org/cgi/man.cgi?query=ndp&sektion=8). 
  RFC Neighbor Discovery for IP version 6: http://tools.ietf.org/html/rfc4861

  Neutron log:
  Command: ['sudo', '/usr/local/bin/neutron-rootwrap', '/etc/neutron/rootwrap.conf', 'ip', 'netns', 'exec', 'qrouter-dfe30f07-f4cd-47db-ac31-347b87435c83', 'arping', '-A', '-I', 'qr-bdaba7ef-6c', '-c', '3', 'fd02::1']
