    bridge: a netlink notification should be sent when those attributes are changed by br_sysfs_br · 047831a9
    Xin Long authored
    Now when we change the attributes of bridge or br_port by netlink,
    a relevant netlink notification will be sent, but if we change them
    by ioctl or sysfs, no notification will be sent.
    
    We should ensure that whenever those attributes change internally or from
    sysfs/ioctl, that a netlink notification is sent out to listeners.
    
    Also, NetworkManager will use this in the future to listen for out-of-band
    bridge master attribute updates and incorporate them into the runtime
    configuration.
    
    This patch is used for br_sysfs_br. and we also need to remove some
    rtnl_trylock in old functions so that we can call it in a common one.
    
    For group_addr_store, we cannot make it use store_bridge_parm, because
    it's not a string-to-long convert, we will add notification on it
    individually.
