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)?

Not supported within IBM, but you can buy OpenPOWER boxes from 3rd 
parties such as Raptor Computing Systems so there may be customers using 
DPDK on POWER with FreeBSD that I don't track.  Adding Piotr Kubaj who 
has commented on POWER/FreeBSD issues in this past.
