Querying frontend status and statistics
***************************************
Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
frontend will run a kernel thread that will periodically check for the
tuner lock status and provide statistics about the quality of the
signal.
The information about the frontend tuner locking status can be queried
doc-rst: linux_tv: simplify references There are lots of internal references in the form: :ref:`foo <foo>` Simplify them to be just: :ref:`foo`.

media: dvb uAPI docs: minor editorial changes Do minor editorial changes to improve documentation readability: - mark literals as such; - add table markups to hint sizes; - define what PES means; - instead of hardcoding devnode numbers to zero (like adapter0/) use a question mark, to indicate that multiple devnodes may exist; - add cross-references where useful.
