 The implementation adds socket options at SOL_PNPIPE level:
 
- PNPIPE_CREATE
-	It accepts an integer argument where-in
-		lower order 16 bits: pn_dev and pn_port pair for remote pep.
-		higher order 16 bits: 8 bit pipe-handle
-
-	It sends a PNS_PEP_CONNECT_REQ on sequenced socket itself. On getting
-	PNS_PEP_CONNECT_RESP, it sends PNS_PEP_CONNECT_REQ to remote pep. On
-	getting response from remote pep, it selects the best possible Flow
-	control mechanism supported by remote-pep (modem) and then it sends
-	PNS_PEP_CREATED_IND to the sequenced socket and to the remote pep.
-
-	It then updates the pipe state associated with the sequenced socket to
-	be PIPE_DISABLED.
+ 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.
 
-   PNPIPE_DESTROY
-	This will send out PNS_PEP_DISCONNECT_REQ on the sequenced socket and
-	the remote pep.
-	It will also update the pipe state associated with the sequenced socket
-	to PIPE_IDLE
+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
