No, we want them on the host level.
The reason for such config is that VMQ and RSS and iSCSI cannot live well together on one windows network interface. So we need to be able to partition physical port into several "virtual". Then enable VMQ's for one partition to be used with hyper-v virtual switch. Enable RSS for the other - that's for LiveMigration traffic. And the last one goes to iSCSI, with offload to hardware, if possible. On top of that we of course need DCBX, to not screw up whole convergent thing up when network becomes saturated.
