I'm not an expert here, but I believe there is a limitation in Hyper-V
(the Windows host hypervisor) where VFs cannot be assigned to the host -
VFs can only be assigned to the guest VMs. (I believe there is no such
limitation with Linux-based hypervisors). Hopefully, someone from
Microsoft can confirm this.
