Title:
  ICMPv6 ML2 rule causing dropped packets in DVR configurations

Status in neutron:
  Fix Released

Bug description:
  There is an Openflow rule installed in install_dvr_process_ipv6() that
  is dropping all egress ICMPv6 packets from a VM on a DVR router.  The
  comment shows it was intended to drop Router Advertisements, but
  doesn't have an icmp_type field to filter them.  Issue noticed by
  trying to ping6 a VM on a "remote" compute node - echo request
  arrives, see echo reply, but it never makes it into br-tun.

  A small change to the code to only filter RAs fixes the problem, patch
  forthcoming.
