For CPU-optimized networking, when mounting filesystems using statless clients, it is possible to use DPDK networking without dedicating cores. This mode is recommended when available and supported by the NIC drivers. In this mode, the DPDK networking uses RX interrupts instead of dedicating the cores.

Note: This mode is supported in most NIC drivers, but not in all, consult https://doc.dpdk.org/guides-18.11/nics/overview.html for compatibility.

AWS (ENA drivers) does not support this mode, hence for CPU-optimized networking in AWS use the UDP Mode.
