NAME
register_netdevice_notifier - register a network notifier block
SYNOPSIS
int register_netdevice_notifier (struct notifier_block * nb);
ARGUMENTS
nb notifier
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.
