queues per bucket. There is a hashing algorithm which should distribute IPv6 reassembly queues across the available buckets in a relatively even way. However, if there is a flaw in the hashing algorithm which allows a large number of IPv6 fragment reassembly queues to end up in a single bucket, a per- bucket limit could help mitigate the performance impact of this flaw. Implement such a limit, with a default of twice the maximum number of reassembly queues divided by the number of buckets. Recalculate the limit any time the maximum number of reassembly queues changes. However, allow the user to override the value using a sysctl (net.inet6.ip6.maxfragbucketsize).
