additional note: I think this is needs more long-term work, so
I'd say it is post-1.5 item. 1.5 tree should be corrected in either
of the following:
- disable icmp6 rate limitation completely
- enable pps-based icmp6 rate limitation, no interval rate limitation
(setting errratelimit = 0 should be okay)
- some other way which can be done quickly enough, with minimal
complexity
