I have feeling DVBv5 API is aimed to transfer data via property cached.
I haven't done much driver for DVBv5 statistics, but recently I
implemented CNR (DVBv5 stats) to Si2168 driver and it just writes all
the values directly to property cache. I expect RF strength (RSSI) is
just similar.

fe->ops.tuner_ops.get_rf_strength() reports its result in u16,
while in DVB APIv5 it should be reported in s64 and by 0.001dBm.
