Export the call to raw_notifier_call_chain so modules can send notifications
on netdev events to the netdev_chain.
Add IFF_SLAVE_DETACH to the list of priv_flags for net_device.
This flag is set by a slave that is about to unregisster from the kernel.
Both changes are used in bonding slaves that wish to inform the bonding master
about coming detachment.
