Sure, I'll reword it! The broader question, however, is this correct for non-Linux/non-DPDK PF drivers? 
For FreeBSD I'll dig into the code, but for VMWARE (and I'd assume Microsoft Windows) it'll be harder.

Do you have any insights on the behavior for the non-open i40e PF drivers?

>From the documentation [1], it's unclear whether non-Linux/non-DPDK PF drivers are supported. My
interpretation was that only DPDK and Linux PF hosts are supported for Fortville NICs.
