If the source side device does not have MQ, RSS or TSO feature, the vDPA device assigned to the VM does not have MQ, RSS or TSO as well. When migrating to a node which has a device with MQ, RSS or TSO, to provide a consistent network device to the guest, to be transparent to the guest, we need to mask out MQ, RSS or TSO in the vDPA device when provisioning. This is an example that management device may have different feature bits than the vDPA device.
Yes. Right.
