From 30c8bd5aa8b2c78546c3e52337101b9c85879320 Mon Sep 17 00:00:00 2001 From: Sridhar Samudrala Date: Thu, 24 May 2018 09:55:13 -0700 Subject: net: Introduce generic failover module 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 migration of VMs with direct attached VFs by failing over to the paravirtual datapath when the VF is unplugged. Signed-off-by: Sridhar Samudrala Signed-off-by: David S.
