> An upcoming feature of IBM VNIC protocol is the ability to configure
> redundant backing devices for a VNIC client. In case of a failure
> on the current backing device, the driver will receive a signal
> from the hypervisor indicating that a failover will occur. The driver
> will then wait for a message from the backing device before
