Description
Register a notifier to be called when network device events occur. The notifier passed is linked into the kernel structures and must not be reused until it has been unregistered. A negative errno code is returned on a failure.
When registered all registration and up events are replayed to the new notifier to allow device to have a race free view of the network device list.
