Add Intel Ethernet Virtual Function device IDs to netuio inf file to support Intel 40GbE and 100GbE deives on Windows VM.Nit: why only VM? Can't VF be used from the host?
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. Ref: https://docs.microsoft.com/en-us/windows-hardware/drivers/network/sr-iov-architecture ranjit m.
