Should we rename all these structs net_failover?
It's possible to extend the concept to storage I think.

[PATCH net-next v7 0/4] Enable virtio_net to act as a standby for a passthru device
The main motivation for this patch is to enable cloud service providers
to provide an accelerated datapath to virtio-net enabled VMs in a
transparent manner with no/minimal guest userspace changes. This also
enables hypervisor controlled live migration to be supported with VMs that
have direct attached SR-IOV VF devices.
Patch 1 introduces a new feature bit VIRTIO_NET_F_STANDBY that can be
used

...of ops to manage the

2. new virtio_net based solution that uses 3 netdev model. In this model,
the failover module provides interfaces to create/destroy additional master
netdev and all the slave events are managed internally.
failover_create()
failover_destroy()
These functions call failover_register()/failover_unregister() with the
master netdev created by the failover module.
