Does this rate-limit all ICMPv6 packets or just ICMPv6 error messages (as 
specified in ICMPv6 specifications).

If all, I believe the default of rate-limiting everything is unacceptable.

Note that in the patch does not seem to add the rate-limit sysctl to any 
functions -- was that to happen in some other patch?
