From 05e00cbf5036929355020dab4837b637203a0742 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Fri, 17 Nov 2006 17:38:47 -0500 Subject: NetLabel: check for a CIPSOv4 option before we do call into the CIPSOv4 layer Right now the NetLabel code always jumps into the CIPSOv4 layer to determine if a CIPSO IP option is present. However, we can do this check directly in the NetLabel code by making use of the CIPSO_V4_OPTEXIST() macro which should save us a function call in the common case of not having a CIPSOv4 option present.
