+	The "Communication CPU to Application CPU Interface" (CAIF) is a packet
+	based connection-oriented MUX protocol developed by ST-Ericsson for use
+	with its modems. It is accessed from user space as sockets (PF_CAIF).
+
+	Say Y (or M) here if you build for a phone product (e.g. Android or
+	MeeGo ) that uses CAIF as transport, if unsure say N.
+
+	If you select to build it as module then CAIF_NETDEV also needs to be
+	built as modules. You will also need to say yes to any CAIF physical
+	devices that your platform requires.
+
+	See Documentation/networking/caif for a further explanation on how to
+	use and configure CAIF.

+	Say Y if you will be using a CAIF based GPRS network device.
+	This can be either built-in or a loadable module,
+	If you select to build it as a built-in then the main CAIF device must
+	also be a built-in.
+	If unsure say Y.
