A pre-requisite for lockless routing lookup is the introduction of modular lookup framework, allowing to attach any longest-prefix-match algorithm implementation to any IPv4/IPv6 fib.

Currently there are plans to use modified DIR-24-8 algorithm from DPDK for both IPv4 and IPv6 families as an example of base lockless implementation.
