Description

Setting mempool size and descriptor sizes to "auto" on e.g. MLX device Suricata calculates it needs 32767 objects per queue and mempool. But in reality, it needs 65535 objects where 32768 RX descriptors fit + extra space for TX descriptors.

Co-found with #8301 when testing with DPDK 25.11 on NVIDIA Connect-X5 card.
