[PATCH net-next-2.6 0/3] bonding,ipv4,ipv6,vlan: Use notifiers to trigger advertisements on failover

[Ben Hutchings]

It is undesirable for the bonding driver to be poking into higher
level protocols, and notifiers provide a way to avoid that.

Ian added NETDEV_NOTIFY_PEERS to trigger gratuitous ARP on VM migration.
We should extend that to unsolicited NAs and propagate it through VLANs,
then treat bonding failover in the same way.

Ben.

I'm going to apply these patches since they clean up so much.

If the concerns brought up by Jay or Brian need to be addressed,
we can either add fixes or in the worst case revert.

Thanks!
