[media] dvb_frontend: Handle all possible DVBv3 values for bandwidth
Browse files Browse the repository at this point in the history
Due to DVB-T2, several new possible values for bandwidth were added.
As the DVBv3 struct were updated to handle them, the core needs to
handle all of them, as a DVBv3 application might try to use it.
