- `TCP_REUSPORT_LB_NUMA` to add/remove a filter associated with the NUMA
  domain.
- `TCP_FUNCTION_ALIAS` when available to fetch the alternate function
  pointer name (or empty), (FreeBSD 14.0 min tough).
- `TCP_BBR_ALGORITHM` for the older BBR TCP stack which backend is used
 `0` netflix, `1` google.
