    neigh: Send netevent after marking neigh as dead · 53f800e3
    Ido Schimmel 提交于
    neigh_cleanup_and_release() is always called after marking a neighbour
    as dead, but it only notifies user space and not in-kernel listeners of
    the netevent notification chain.
    
    This can cause multiple problems. In my specific use case, it causes the
    listener (a switch driver capable of L3 offloads) to believe a neighbour
    entry is still valid, and is thus erroneously kept in the device's
    table.
    
    Fix that by sending a netevent after marking the neighbour as dead.
