    @param off_link - The prefix is off link (it is not configured on the interface)
                      Configures the L-flag, When set, indicates that this
                      prefix can be used for on-link determination.
    @param no_autoconfig - Setting for the A-flag. When
                           set indicates that this prefix can be used for
                          stateless address configuration.
    @param no_onlink - The prefix is not on link. Make sure this is consistent
                       with the off_link parameter else YMMV
    @param is_no - add/delete

                     that the prefix is valid for the purpose of on-link
                     determination.  A value of all one bits

                     seconds (relative to the time the packet is sent)
                     that addresses generated from the prefix via
