[PATCH net-next v10 2/4] net: Introduce generic failover module
...sets of interfaces to the paravirtual drivers.
1. For paravirtual drivers like virtio_net that use 3 netdev model, the
the failover module provides interfaces to create/destroy additional
master netdev and all the slave events are managed internally.

A failover netdev is created that acts a master device and controls 2
slave devices. The original virtio_net netdev is registered as 'standby'
netdev and a passthru/vf device with the same MAC gets registered as
'primary' netdev. Both 'standby' and 'failove...

[PATCH net-next v8 0/4] Enable virtio_net to act as a standby for a passthru device
This is another update based on feedback from MST and Stephen on the
last patchset. Hopefully this series can be integrated and any further
enhancements can be made on top of this patchset.
v8:
- Made the failover managment routines more robust by updating the feature
bits/other fields in the failover netdev when slave netdevs are
registered/unregistered. (mst)
- added support for handling

[PATCH net-next v10 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
