+ This enables the XFRM (IPSec) networking security hooks.
+ If enabled, a security module can use these hooks to
+ implement per-packet access controls based on labels
+ derived from IPSec policy. Non-IPSec communications are
+ designated as unlabelled, and only sockets authorized
+ to communicate unlabelled data can send without using
+ IPSec.
