.SH "DESCRIPTION"
.PP
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\&.
.PP
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\&.
