When a bridge binding flag is changed for a vlan interface, the vlan_dev_change_flags function in the 8021q module is called. Currently, this function only sets the flag for the vlan interface and returns, which results in a buggy behavior; it also needs to let the bridge module module know that upper device for the bridge has changed by propagating NETDEV_CHANGEUPPER event. This event can be triggered using call_netdevice_notifiers_info function, so export this function.
