As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.
