As a consequence, 8 bytes can be re-allocated to dynamic fields, and bonus... the mempool pointer can be promoted to the first half of mbuf! This mbuf layout change is important to allow adding more features (consuming more dynamic fields) during the next year and can bring some performance improvement.
