[PATCH v5 33/80] net/ntnic: add FLM module

[Serhii Iliushyk <sil-plv@napatech.com>]

From: Danylo Vodopianov <dvo-plv@napatech.com>

The Flow Matcher module is a high-performance stateful SDRAM lookup
and programming engine which supported exact match lookup
in line-rate of up to hundreds of millions of flows.
