rtnetlink: Updates to rtnetlink_event()
First is the patch to add IFLA_EVENT attribute to the netlink message. It
supports only 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.
Second, I remove duplicate messages that a result of a change to bonding
options. If netlink is used to configure bonding options, 2 messages
are generated, one as a result NETDEV_CHANGEINFODATA event triggered by
bonding code and one a result of device state changes triggered by
netdev_state_change (called from do_setlink).
V6: Updated names and refactored to make it less tied to netdev events.
(From David Ahern)
V5: Rebased. Added iproute2 patch to the series.
V4:
* Removed the patch the removed NETDEV_CHANGENAME from event whitelist.
It doesn't trigger duplicate messages since name changes can only be
done while device is down and netdev_state_change() doesn't report
changes while device is down.
* Added a patch to clean-up duplicate messages on bonding option changes.
V3: Rebased. Cleaned-up duplicate event.
V2: Added missed events (from David Ahern)
