fixes:
  - Prior to Mitaka, the settings that control the frequency of
    router advertisements transmitted by the radvd daemon were
    not able to be adjusted. Larger deployments may wish to decrease
    the frequency in which radvd sends multicast traffic. The 'min_rtr_adv_interval'
    and 'max_rtr_adv_interval' settings in the L3 agent configuration file
    map directly to the 'MinRtrAdvInterval' and 'MaxRtrAdvInterval' in the generated
    radvd.conf file. Consult the manpage for radvd.conf for more detailed information.
