This is a version 3 series came out of the conversation that started as a result my first attempt to add netdevice event info to netlink messages.
First, let's clean-up the duplicate notifications for NETDEV_CHANGNAME event. We get a message from the event handler as well as a result of do_setlink(). The two messages are identical, so remove the event. Second, update the original patch to add IFLA_EVENT attribute to the link message to only support currently white-listed events. Like before, this is just an attribute that gets added to the rtnetlink message only when the messaged was generated as a result of a netdev event. In my case, this is necessary since I want to trap NETDEV_NOTIFY_PEERS event (also possibly NETDEV_RESEND_IGMP event) and perform certain actions in user space. This is not possible since the messages generated as a result of netdev events do not usually contain any changed data. They are just notifications. This patch exposes this notification type to userspace. I will also update my patch to iproute that will show this data through 'ip monitor'. V3: Rebased. Cleaned-up duplicate event.
