+         OCF-Linux is a Linux port of the OpenBSD/FreeBSD Cryptographic
+         Framework (OCF). This port aims to bring full asynchronous HW/SW
+         crypto acceleration to the Linux kernel and applications
+         running under Linux.
+
+         You need to enable the OCF linux kernel extension or provide
+         a prepatched kernel to make this option useful.
