> This patch set adds a longest prefix match algorithm that can be used
> to match IP addresses to a stored set of ranges. It is exposed as a
> bpf map type.
>
> Internally, data is stored in an unbalanced tree of nodes that has a
> maximum height of n, where n is the prefixlen the trie was created
> with.
>
> Note that this has nothing to do with fib or fib6 and is in no way meant
> to replace or share code with it. It's rather a much simpler

>
> Patch 1/2 adds the implementation, 2/2 an extensive test suite and 3/3
> has benchmarking code for the new trie type.

> Feedback is much appreciated.
Series applied, thank you.
