+ioctl NET_ADD_IF
+****************
+
+Name
+====
+
+NET_ADD_IF - Creates a new network interface for a given Packet ID.
+
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, struct dvb_net_if *net_if )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <frontend_f_open>`.
+
+``request``
+    FE_SET_TONE
+
+``net_if``
+    pointer to struct :ref:`dvb_net_if <dvb-net-if>`
+
+
+Description
+===========
+
+The NET_ADD_IF ioctl system call selects the Packet ID (PID) that
+contains a TCP/IP traffic, the type of encapsulation to be used (MPE or
+ULE) and the interface number for the new interface to be created. When
+the system call successfully returns, a new virtual network interface is
+created.
+
+The struct :ref:`dvb_net_if <dvb-net-if>`::ifnum field will be
+filled with the number of the created interface.

+struct dvb_net_if description
+=============================

+
+       -  Description
+
+    -  .. row 2
+
+       -  pid
+
+       -  Packet ID (PID) of the MPEG-TS that contains data
+
+    -  .. row 3
+
+       -  ifnum
+
+       -  number of the DVB interface.
+
+    -  .. row 4
+
+       -  feedtype
+
+       -  Encapsulation type of the feed. It can be:
+	  ``DVB_NET_FEEDTYPE_MPE`` for MPE encoding or
+	  ``DVB_NET_FEEDTYPE_ULE`` for ULE encoding.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
