Where's the patch description? For sure a patch like that deserves to be
well described.

The above for sure belongs to statistics API. It should be addressed together
with the other statistics API bits.

We shouldn't mix statistics with DVB frontent properties.

Btw, this is basically the same case as on ISDB-T: the layer that handles the channel
data (TPC, on ATSC M/H; TPS on DVB; TMCC on ISDB) provides statistics about
the frontend. However, the DVBv3 quality ioctl's are prepared to handle only
DVB parameters, and fails with more modern delivery systems.

We should apply a patch that will fix this one for all, like the one proposed by:
