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.
