An ioctl FE_GET_FRONTEND on the frontend device returns a struct
dvb_frontend_parameters which contains all the tuning and modulation
parameters, including the frequency. You need to tune on the frequency
first, of course.
In the French DVB-T network, all terrestrial_delivery_descriptors in the
NIT are generic. All frequencies are 0xFFFFFFFF and all modulation
parameters are those of the average MFN transmitters in the country.
They are incorrect for all SFN transmitters and some specific transmitters
(including the local services "L8" multiplex).
Otherwise, the most recent (March 31) list of the French DVB-T frequencies
by transmitter is available at:
