    vxlan: Add extack to switchdev operations · 4c59b7d1
    Petr Machata authored
    There are four sources of VXLAN switchdev notifier calls:
    
    - the changelink() link operation, which already supports extack,
    - ndo_fdb_add() which got extack support in a previous patch,
    - FDB updates due to packet forwarding,
    - and vxlan_fdb_replay().
    
    Extend vxlan_fdb_switchdev_call_notifiers() to include extack in the
    switchdev message that it sends, and propagate the argument upwards to
    the callers. For the first two cases, pass in the extack gotten through
    the operation. For case #3, pass in NULL.
    
    To cover the last case, extend vxlan_fdb_replay() to take extack
    argument, which might come from whatever operation necessitated the FDB
    replay.
