Description
===========
The NET_GET_IF ioctl uses the interface number given by the struct
-:ref:`dvb_net_if <dvb-net-if>`::ifnum field and fills the content of
-struct :ref:`dvb_net_if <dvb-net-if>` with the packet ID and
+:c:type:`dvb_net_if`::ifnum field and fills the content of
+struct :c:type:`dvb_net_if` with the packet ID and
encapsulation type used on such interface. If the interface was not
created yet with :ref:`NET_ADD_IF <net>`, it will return -1 and fill
the ``errno`` with ``EINVAL`` error code.
