Nick, Thanks for the reply. I am more looking from virtualization perspective. If I have attached VFs to VMs and switching happens in NIC, OVS will not know what is happening in NIC. Also, the switching inside NIX is based on ethernet MAC address and VLAN. We will not be able to take the full advantage of other OVS features like VxLAN encapsulation etc at this moment with VFs. Also, number of VFs will be limited and ifd we need to switch between VF and a software interface, it will not be possible. This is what I mean by support in OVS. Is there any specification whichcal tell HW requirements so that OVS can work in this situation seamlessly.
