                    Current, iavf
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org

I am trying to use the SR-IOV ability in a virtual machine. But that
does not work. The host has the latest Intel drivers for the x710
network adapter. Second Generation Virtual Machine with GERERIC
Recompiled FreeBSD-Current Core for today. Host is Windows Server 2019
with Intel drivers (i40ea68.sys 1.10.128.0).
