-config SECURITY_SELINUX_ENABLE_SECMARK_DEFAULT
-	bool "NSA SELinux enable new secmark network controls by default"
-	depends on SECURITY_SELINUX
-	default n
-	help
-	  This option determines whether the new secmark-based network
-	  controls will be enabled by default.  If not, the old internal
-	  per-packet controls will be enabled by default, preserving
-	  old behavior.
-
-	  If you enable the new controls, you will need updated
-	  SELinux userspace libraries, tools and policy.  Typically,
-	  your distribution will provide these and enable the new controls
-	  in the kernel they also distribute.
-
-	  Note that this option can be overridden at boot with the
-	  selinux_compat_net parameter, and after boot via
-	  /selinux/compat_net.  See Documentation/kernel-parameters.txt
-	  for details on this parameter.
-
-	  If you enable the new network controls, you will likely
-	  also require the SECMARK and CONNSECMARK targets, as
-	  well as any conntrack helpers for protocols which you
-	  wish to control.
-
-	  If you are unsure what to do here, select N.
