Overview
|
|
========
|
|
|
|
The failover module provides a generic interface for paravirtual drivers
|
|
to register a netdev and a set of ops with a failover instance. The ops
|
|
are used as event handlers that get called to handle netdev register/
|
|
unregister/link change/name change events on slave pci ethernet devices
|
|
with the same mac address as the failover netdev.
|
|
|
|
This enables paravirtual drivers to use a VF as an accelerated low latency
|
|
datapath. It also allows live migration of VMs with direct attached VFs by
|
|
failing over to the paravirtual datapath when the VF is unplugged.
