+ Please note that the kernel crypto API contains the AEAD givcrypt
+ API (crypto_aead_giv* and aead_givcrypt_* function calls in
+ include/crypto/aead.h). This API is obsolete and will be removed
+ in the future. To obtain the functionality of an AEAD cipher with

+ For example, rfc4106(gcm(aes)) is the AEAD cipher with external
+ IV generation and seqniv(rfc4106(gcm(aes))) implies that the kernel
+ crypto API generates the IV. Different IV generators are available.

+<para>Tuning into a Digital TV physical channel and starting decoding it
+ requires changing a set of parameters, in order to control the
+ tuner, the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
+ antenna subsystem via Satellite Equipment Control (SEC), on satellite
+ systems. The actual parameters are specific to each particular digital
+ TV standards, and may change as the digital TV specs evolves.</para>
+<para>In the past, the strategy used was to have a union with the parameters

+ there. The problem is that, as the second generation standards appeared,

-<para>The kind of parameters passed to the frontend device for tuning depend on
-the kind of hardware you are using.</para>
-<para>The struct <constant>dvb_frontend_parameters</constant> uses an
-union with specific per-system parameters. However, as newer delivery systems
-required more data, the structure size weren't enough to fit, and just
-extending its size would break the existing applications. So, those parameters
-were replaced by the usage of <link linkend="FE_GET_SET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> ioctl's. The
-new API is flexible enough to add new parameters to existing delivery systems,
-and to add newer delivery systems.</para>
-<para>So, newer applications should use <link linkend="FE_GET_SET_PROPERTY">

+<para>The struct <constant>dvb_frontend_parameters</constant> uses an

+<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> ioctl's. The
+new API is flexible enough to add new parameters to existing delivery systems,
