    vxlan: Add switchdev notifications · 9a997353
    Petr Machata authored
    When offloading VXLAN devices, drivers need to know about events in
    VXLAN FDB database. Since VXLAN models a bridge, it is natural to
    distribute the VXLAN FDB notifications using the pre-existing switchdev
    notification mechanism.
    
    To that end, introduce two new notification types:
    SWITCHDEV_VXLAN_FDB_ADD_TO_DEVICE and SWITCHDEV_VXLAN_FDB_DEL_TO_DEVICE.
    Introduce a new function, vxlan_fdb_switchdev_call_notifiers() to send
    the new notifier types, and a struct switchdev_notifier_vxlan_fdb_info
    to communicate the details of the FDB entry under consideration.
    
    Invoke the new function from vxlan_fdb_notify().
