This should make NetLabel more consistent with other kernel generated audit messages specifying configuration changes.

* This file manages the domain hash table that NetLabel uses to determine
|
|
* which network labeling protocol to use for a given domain. The NetLabel
|
|
* system manages static and dynamic label mappings for network protocols such
|
|
* as CIPSO and RIPSO.
