-Phonet Pipe-controller Implementation
--------------------------------------
-
-Phonet Pipe-controller is enabled by selecting the CONFIG_PHONET_PIPECTRLR Kconfig
-option. It is useful when communicating with those Nokia Modems which do not
-implement Pipe controller in them e.g. Nokia Slim Modem used in ST-Ericsson
-U8500 platform.
-
-The implementation is based on the Data Connection Establishment Sequence
-depicted in 'Nokia Wireless Modem API - Wireless_modem_user_guide.pdf'
-document.
-
-It allows a phonet sequenced socket (host-pep) to initiate a Pipe connection
-between itself and a remote pipe-end point (e.g. modem).
-
-The implementation adds socket options at SOL_PNPIPE level:
-
- PNPIPE_PIPE_HANDLE
-	It accepts an integer argument for setting value of pipe handle.
-
-  PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe
-    is disabled. If the value is non-zero, the pipe is enabled. If the pipe
-    is not (yet) connected, ENOTCONN is error is returned.
-
-The implementation also adds socket 'connect'. On calling the 'connect', pipe
-will be created between the source socket and the destination, and the pipe
-state will be set to PIPE_DISABLED.
-
-After a pipe has been created and enabled successfully, the Pipe data can be
-exchanged between the host-pep and remote-pep (modem).
-
-User-space would typically follow below sequence with Pipe controller:-
--socket
--bind
--setsockopt for PNPIPE_PIPE_HANDLE
--connect
--setsockopt for PNPIPE_ENCAP_IP
--setsockopt for PNPIPE_ENABLE
+  PNPIPE_HANDLE is a read-only integer value. It contains the underlying
+    identifier ("pipe handle") of the pipe. This is only defined for
+    socket descriptors that are already connected or being connected.
