+ default n
+ help
+ 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 a module. You will also need to say Y (or M) to any CAIF
+ physical devices that your platform requires.
+
+ See Documentation/networking/caif for a further explanation on how to
+ use and configure CAIF.
+
+config CAIF_DEBUG
+ bool "Enable Debug"
+ depends on CAIF
+ default n
+ help
+ Enable the inclusion of debug code in the CAIF stack.
+ Be aware that doing this will impact performance.
+ If unsure say N.
+
+config CAIF_NETDEV
+ tristate "CAIF GPRS Network device"
+ depends on CAIF
+ default CAIF
+ help
+ 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.
+
+config CAIF_USB
+ tristate "CAIF USB support"
+ depends on CAIF
+ default n
+ help
+ Say Y if you are using CAIF over USB CDC NCM.
+ 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 N.
