Is there a use for the cell ids from TPS?
Is anything else missing for DVB-T?

If dvbh_parameters exceeds dvbt_parameters in size we
cannot add it to FE_SET_FRONTEND without breaking
binary compatibility.

So if we need FE_SET_FRONTEND_NEW (or _EX or whatever) anyway, we could
make a clean design with a "standard" and "flags" field (replacing
FE_SET_STANDARD and FE_SET_FRONTEND_TUNE_MODE). And add some "u8
reserved[32]" at the end for future extensions.

What do you think?
