Bruce, David, Thomas,

Is DPDK actually supported on Power9 FreeBSD? Is anyone using this combination? How can we address the open question of what exactly does sysctl -n vm.ndomains return on a Power9 FreeBSD system? Or should we just leave it as is? Or maybe add 1 to the output (as we do in other cases)?
