Rather than allocating however much memory userspace asks for we only allocate enough for a handful of states, and copy to userspace for each completed row. We start out with enough space for 16 states (per row), but grow that as required. In most configurations we expect at most a handful of states per row (more than that would have other negative effects on packet processing performance).
