--- Comment #32 from lists@freshlybrewed.coffee ---
I did eventually find a solution for this. I found a forum post which clued me
into the fact that the intel-ixl-kmod port has an SR-IOV option, which is not
enabled in the package. Installing the port with SR-IOV support enabled solves
the problem.

 1. Configure intel-ixl-kmod port with SR-IOV support, and "make install"
 2. Add if_ixl_updated_load="YES" to /boot/loader.conf
 3. Reboot
 4. Configure VFs with iovctl
 5. Start VM
