    rtnl: Add support for netdev event to link messages · def12888
    Vlad Yasevich authored
    When netdev events happen, a rtnetlink_event() handler will send
    messages for every event in it's white list.  These messages contain
    current information about a particular device, but they do not include
    the iformation about which event just happened.  The consumer of
    the message has to try to infer this information.  In some cases
    (ex: NETDEV_NOTIFY_PEERS), that is not possible.
    
    This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT
    that would have an encoding of the which event triggered this
    message.  This would allow the the message consumer to easily determine
    if it is interested in a particular event or not.
